2020-04-10T18:37:00.000+05:00

What Is The Sand Replacement Method?

(The Standard for this method is, AASHTO - T - 191)

This Sand Replacement Method is used in the field to determine the soil compaction of required area that is compacted by some rolling vehicles, to measure the compaction by using Soil Replacement Method.

The other name of Soil Replacement Method is a Sand Cone Method. This whole process is called Field Density Test.

Sand Replacement Method

Apparatus Of Field Density Test:

Sand Pouring Cylinder
Calibrating Cone
Moisture Container
Metal Tray with a Central Hole
Dry Sand (passing through 600 micron sieve)
Balance
Scraper Tool
Brush
Oven
Spoon

Procedure Of Sand Replacement Test:

After calibrating the apparatus of field density test, take the initial weight of the sand with bottle (sand placed in the bottle) before going to site.

At the site keep the base plate down where test will operate, and digging out the soil from hole of base plate about 6 inches deep and diameter is same with base plate/ density plate, and collecting that excavated soil and weight it.

After this fill calibrated cylinder with sand and put on the base plate hole and then opened the valve/stopper.

When sand stops flowing and remove the cylinder from test hole of base plate.

Then weight the remaining sand with apparatus (in which sand is placed). Note all the values of sand and excavated soil.

After weighting the excavated soil and take some sample in weighted container for determination of moisture contents in the oven.

Now going to calibrate the sand replacement method first to operate the test,

Calibration Of Cone Method:

The standard code is,

ASTM D – 1556

AASHTO - T – 181 - 191

First to take calibrating container and fill it with sand and weight it (e.g. 8000g) by using balance machine, and now this cone places on base plate, then opened the shutter of a cone and movement of sand will start, when sand stopped to move out the closed the shutter.

Remove the Cone from base plate and weight again of remaining sand (e.g. 6242g).

This sand should be clean and should take passed of sieve No. 16 and retained of sieves No. 30.

This method repeated three times same like first one that is mention above.

Calculation For Calibrated Cylinder:

Apparatus:

Cylindrical Mold = Diameter is 4” (10.16 cm) or 6” (15.24 cm),

Base plate & collar of 2 inches (5.08 cm).

Rammer = weighing 5.5 lbs (2.5 kg) , circular face of 2” diameter.

Sensitive Balance

Thermostatically controlled oven

Tray & scoop

Graduated cylinder

Mixing tools (spoon, trowel, spatula).

Proctor / Soil Compacted Test:

It is a given soil sample, so that type of soil is denser and receive maximum dry laboratory experimental test to identify the moisture contents in the density.

First to take the sample of soil from the site, which are being tested so, Sieve that soil through No: 4 sieve, and that sieve will reject the coarser materials. From that sample we take about, 3 kg of soil, and add some water to increase its water content to about 5%, below the estimated optimum moisture content.

For example (for coarse grained the initial contents of water of soil is 4% and for fine-grained soil 10% initial water content is preferable). Then Mix that 3 kg soil sample with scoop. Then clean the mold and measure its volume, height and weight without the collar.

After filling the mold and fit the collar with cylindrical mold & compact the moist soil in five equal layers by the hammer with evenly distributed blows to each layer. Use 56 blows (6 inches diameter) mold with collar. We can also use 4 inches diameters mold with 25 blows.

Then remove the collar trim the compacted soil even with the top of the mold with a straight steel edge. Clean outside of the mold and base plate and weight this mold with sample of soil.

Proctor Test

Remove the soil from the mold, split it and take about 100 grams sample to keep in Oven for water content determination.

Break the soil lamps, and again mix it with remaining soil in the tray.

Add more water to increase the water content by 2% and repeat the compaction procedure for 4 times each increment of water until the mass of the compacted soil decreases.

Calculate Water contents for each trail & corresponding dry density.

Plot the compaction curve between water-content & dry density as ordinate.

Proctor Test Curve

Note the water content against the peak of the curve as optimum moisture content & the corresponding dry density as maximum dry density.

Calculation:

All these parameters should measure first to calculate the values of maximum Density and percentage of moisture contents

Density = ?

Weight of the mold = 4443

Volume of Mold = 2133

Weight of Mold + wet soil = 9000

CAN No. = B-1

CAN weight (empty) = 69.6

Weight of CAN + wet soil (before placing soil in Oven) = 320.7

Weight of CAN + dry soil (after dry from oven) = 313.7

Wet soil weight = total weight - mold weight

= 9000 - 4443 = 4557 g

wet density = wt / volume = 4557 / 2133 = 2.136 g/cm3

Dry Density = wt / volume =

Moisture Contents = ? (This step is after to out the container from oven)

wt of container =

wt of soil wet soil + container =

wt of dry soil + container =

wt of water =

wt of dry soil =

Moisture =

To measure these all values step by step then you can easily calculated and determine the moisture content of soil.

Sand Equivalent Test

2020-04-05T23:31:00.000+05:00

What Is Sand Equivalent?

The sand equivalent test is a fast subject test to show the relative proportions of excellent dust or clay-like materials in nice combination (or granular soils). The term “sand equivalent” expresses the idea that most pleasant aggregates are combos of proper coarse debris (e.g. sand) and normally undesirable clay or plastic fines and dirt (ASTM).These materials can coat combination debris and prevent right asphalt binder-combination bonding. In the sand equivalent test, a sample of combination passing the No. 4 (4.seventy five mm) sieve and a small quantity of flocculating answer are poured right into a graduated cylinder. The pattern is then irrigated with extra flocculating solution forcing the clay-like fabric into suspension above the sand. After a prescribed sedimentation period, the peak of flocculated clay and height of sand are decided and the sand equal is expressed as a ratio of the height of sand over the height of clay. Higher sand equivalent values indicate “cleaner” (less first-rate dirt or clay-like materials) combination.

Apparatus:

Graduated cylinder = Inside diameter = 1.25-in (31.8-mm), Height = 17-in (432-mm)

Procedure Of Sand Equivalent:

Sand Equivalent Test Equipment

When we start to examine the sand equivalent test for mixture used for bituminous materials, including hot blend asphalt, hot-blend cold-laid, and others micro surfacing. Dry the test sample in an Oven with steady weight at 110 ± 5 °C. Oven-dry pattern of limestone rock asphalt aggregates at 60 ± 3 °C. Tests on damp samples will typically give decrease values than assessments on oven-dried samples. It is permissible now not to dry the pattern to store time, but if the test values are close to or underneath the required minimal, then retest the sample inside the oven-dry condition. After drying in Oven then cast off sample from oven and allows it to cool to room temperature. Using the No. 4 (4.75 mm) sieve, separate the sample into portions, breaking apart lumps that encompass particles obviously finer that the No. 4 (4.75 mm) sieve.

Graduated Cylinder With Sample

Using the No. 4 (4.75 mm) sieve, separate the sample into portions, breaking apart lumps that encompass particles obviously finer that the No. 4 (4.75 mm) sieve.

Secure the sand equivalent take a look at pattern from the element passing the No. 4 (4.75 mm) sieve by cautiously reducing the amount of cloth to laboratory test size.

Split or area the material to attain a minimum 500-g pattern, to make certain consultant samples when running with a fabric that is predominantly coarse No. 4 (4.75 mm) to No. 8 (2.36 mm), separate the sample into sizes No. 4 (4.75 mm) to No. 8 (2.36 mm) and minus No. 8 (2.36 mm), after which recombine the cloth in proper proportions to provide a uniform sample. Strike off the extra cloth the usage of a straight aspect or spatula. Do now not compact the sample prior to putting it off.

Performing the Sand Equivalent Test:

The sample is placed in the measuring CAN then transfer the sample into the plastic cylinder by using the small funnel.

Siphon 4 (0.1 in) is used to transfer liquid of calcium chloride solution into the plastic cylinder. Check the agitator tube to be certain that the solution flows freely. Then stopper the cylinder. After this process keep the cylinder with whole contents in undisturbed place, free of any vibration, for approximately 10 minutes.

Mechanical shaker: Set the timer and shake for 45 seconds.

Manual shaker: Place the cylinder in a manual shaker and shake for 100 cycles.

Hand: Shake the cylinder by hand in a horizontal linear motion for 96 cycles, and remove the stopper, to wash the wall of cylinder into the mixture, using a minimum amount of solution. Replace stopper in the end of cylinder. Wash down the cylinder wall with the solution.

Continue smoothly jabbing the agitator tube up and down with a mild twisting motion at the same time as slowly rotating the cylinder in a vertical role to flush the fine clay-like material into suspension above the coarse sand Continue the operation till the cylinder is crammed to the 15 in. (381 mm) mark.

Slowly remove the agitator tube without shutting off the flow, so the level of the liquid is maintained at 15 in. (381 mm).

Regulate the glide of the answer and regulate the extent of way to 15 in.when the agitator tube is absolutely withdrawn. Allow the cylinder and contents to face undisturbed for 20 minutes. Start the timing straight away after the elimination of the agitator tube.

Settlement Of Sediments

After the 20-minutes the sediments are settled down, read the extent of the pinnacle of the clay suspension and report the reading.

If there's no clean line of clay meniscus at the stop of the given time of sediments settling, maintain permitting the fabric to stand undisturbed until the division is clean.

Read and document the level of the clay layer and the total sedimentation time.

When using the weighted foot assembly with sand analyzing indicator, gently lower the foot meeting into the cylinder until it comes to relaxation at the sand. Very lightly tilt the assembly until the indicator touches the commencement marks at the cylinder. Tilt meeting lower back to vertical before taking analyzing. Read the extent indicated with the aid of the pinnacle fringe of the indicator and subtract 10 in. (254 mm). Record this reading because the sand analyzing.

Calculation Of Sand Equivalent Test:

To calculate the values of sand equivalent test is closely by 0.1 inch

Formula Of SE:

SE = Sand / Clay * 100

For Example,

SE = 3.1 / 6.9 * 100 = 44.9

It can be written as 45.

Know, How To Become A Material Engineer:

How to become a good material or QC engineer? This is a simple question that everyone ask. Here we discuss and share some materials that are helpful to become a Material Engineer in civil construction industries. Material engineer is the very interesting and high payer salary field, which is full of knowledge about materials testing on their specification.

Material Engineer develops procedure and check substances used in products. Material Engineer creates and observe substances on the atomic level. They have a look at the houses and shape of metals, ceramics, plastics, composites and others substances.

Material Engineer helps to selecting materials for specific products and develops new ways to use materials. They design direct and monitor the testing of materials in different environments. They will determine causes of product failures and develop innovative ways the product won’t fail. Material Engineer often works on teams with other engineers. Some degrees are playing major role to become a Material Engineer/QC Engineer.

A bachelor's/Undergraduate degree in materials science, Geology, Geophysics and Civil Engineering or a related field is needed for entry-level jobs. Materials scientists can also most important in chemistry or physics and extensive work enjoyable to qualify for new jobs.

If someone have no field experience in construction site and no ideas about testing materials so, here we share every information that are used in fields and as well as Labs.

Become a material engineer to notice some points that are given below,

Materials Quality: First and important role is to check out the materials and testing and inspection of materials (Sands, Cement, Aggregates and Steels) on site.
Storage Of Materials: To check out location, placement area, condition of that area which is dry or not and also that location is approachable or not, it should be near to working area.
Schedule Of Work: It is important to time measurement of project, how many days required to complete this project and every structure should be complete on required time. That is must be knows about that all processes of whole field.
Report Site Activities: It means that make a manual files for all structure that are on the way and completed to report to his senior engineers.
Checklist Of Various Work: Keep record of all activities which are under construction and have constructed that are PPC, RCC, Reinforcement, Plasters etc. Listing of all workability’s of daily currying of structure on site.

These are the main responsibilities of a good Material Engineer in civil construction industries.

Inspite of this, we talk about on point # 1 that is Quality of Materials, how to checkout on site.

To checking the quality of materials by using the method of Testing Of Materials.

Materials Testing is the major role with standard specification in Construction industries.

Some major TESTS are required to use in construction for Material Engineers and Lab Technicians that are used to identify the quality of materials.

Materials Tests

Sand EquivalentTest
Proctor Test
Plasticity Index

Sieve Analysis
Slump Test
Compressive Strength Of Concrete

These are the Tests that are used in construction with different specifications of different companies. To follows these techniques to become a good material engineer and lab technician in different companies.

Concrete and Its Types

2020-03-26T10:53:00.000+05:00

When we say concrete within the building trade, we truly suggest strengthened concrete. Its complete call is bolstered (reinforcement) concrete, or RCC. RCC is concrete that includes metal bars, known as reinforcement bars, or rebars. This mixture works very well, as concrete could be very sturdy in compression, smooth to produce at web page, and inexpensive and metal may be very robust in tension.

To make strengthened concrete, one first makes a mould, called formwork, so one can include the liquid concrete and provide it the shape and shape we need. Then one looks at the structural engineer's drawings and placed inside the metallic reinforcement bars, and ties them in place the usage of wire. The tied metal is called a reinforcement cage, because it's far shaped like one. Once the steel is in place, one can begin to put together the concrete, by means of mixing cement, sand, stone chips in a variety of sizes, and water in a cement mixer, and pouring inside the liquid concrete into the formwork till precisely the right stage is reached.

The concrete will become difficult in a rely on of hours, however takes a month to attain its complete power. Therefore, it also includes propped up until that period. During this time the concrete have to be cured, or supplied with water on its surface, which it desires for the chemical reactions inside to continue properly.

It is known as concrete blend design. A suitable blend fashion designer will begin with the properties which might be desired inside the mix, then take many elements into account, and paintings out a detailed blend design. A website online engineer will often order a distinct form of mix for a specific purpose. For example, if he is casting a skinny concrete wall in a tough-to-reach area, he'll ask for a mix this is extra (flowable) than stiff. This will permit the liquid concrete to flow by means of gravity into each corner of the formwork.

For maximum production applications, however, a preferred blend is used. Common examples of cutting corner of aggregates mixes are (M-20, M-30, M-40) concrete, where in the range refers to the strength of the concrete in n/m3. Therefore, M-30 concrete can have a compression energy of 30 n/mm2. A popular mix might also specify the maximum combination size. Aggregates are the stone chips used in construction concrete. If an engineer specifies M-30 / 20 concrete, he desires M-30 concrete with a maximum aggregate length of 20 mm.

Concrete

He does NOT need concrete with an energy of among 20-30 n/mm2, that is a not unusual location misinterpretation in a few parts of the world.

Concrete that is solid in region in its mildew is called cast-in-situ concrete. Concrete members which can be forged in a concrete manufacturing facility and then shipped to website are referred to as precast concrete.

Types Of Concrete:

Different types of concrete are given below,

High Strength Concrete:

The most fundamental and important assets of concrete is its compressive strength. Concrete with a compressive energy of 40Mpa (5,800 psi) is known as excessive strength concrete. High-overall performance approach that the concrete has one or extra of the subsequent properties: low shrinkage, low permeability, an excessive modulus of elasticity, or excessive strength.

High Performance Concrete:

It is a new time period for some concretes being evolved today. It is a reasonably broad time period that describes concretes that outperform “normal”, everyday concrete in a single or extra characteristics such as lifespan, lifespan in corrosive environments, permeability, density, ease of placement, or many other parameters.

High overall performance concrete is a concrete mixture, which possess high durability and high electricity when compared to standard concrete. This concrete contains one or extra of contentious substances consisting of fly ash, Silica fume or floor granulated blast furnace slag and typically a superb plasticize.

Lightweight Concrete:

Lightweight concrete may be described as a kind of concrete which incorporates an expanding (mixing) agent in that it will increase the quantity of the combination while giving additional features including nailbility and lessened the lifeless weight.

It is made by means of the usage of small, lightweight aggregates, together with small balls of styrofoam (thermocole) or by means of including foaming sellers to the mixture of concrete. Lightweight concretes have less strength, The pleasant is example is aerated autoclaved concrete (AAC) blocks used for making walls. Also known as cellular concrete or aerated concrete.

Sprayed Concrete or Shotcrete:

You could sincerely spray concrete onto a floor to shape a thick, uneven coating. This method isn't the same as other concreting methods in that the concrete isn't always poured into a form or mould. Sprayed concrete is a technique of applying concrete that is typically self-helping without the want for form work.

Water Resistant Concrete:

It is a ordinary concretes are permeable to water; that is, they permit water to skip through. Water resistant concretes are engineered to have nice particle cement replacements that don't permit water to skip through. These are very beneficial for construction underneath ground, like basements, in addition to water keeping structures like water tanks and dams, and of route marine structures like jetties and bridges.

What Is The Foundation and Its Types:

2020-03-25T17:44:00.001+05:00

Foundation:

Foundation is the bottom portion of a structure, which transmits the weight into the assisting soil. The main cause of basis is to distribute the whole weight of the superstructure over a big region of soil.

In this lecture we will talk about sorts of foundation, there are two types of foundation, and the first one is shallow foundations the second one is deep foundations.

let's talk about the factor affect the choice of a foundation there are primary factor and secondary factor the bible factor effect the choice of foundation are subsurface oil under gird water conditions suit actual requirements clothing foundation loads building configurations and depth. Second a factor that may be important include concession method critic access and working space environmental, factor including noise traffic and spousal of earth and water building codes and regulations time available for cross section construction risks.

So now we are speaking about shallow foundation,

Shallow foundation:

Shallow foundations are those that transfer the load to the earth of the base of the color of all of the subset structure. so shallow foundation transferred the load of the column or the wall at the base of sub structure shallow foundation types

Example of shallow foundations is,

Types Of Footing:

Columns Footing
Strip Footing
Mat Foundation
Combined Footing

Now we will talk about when we use average type of a shallow foundation.

The first type is,

i. Column Footing:

It's simple and most economical an oscillating folding is used to support a single column, we use column footing when columns are not too close this base notes on footing are less and the safe bearing capacity of soil is generally high. So it support the load coming the phone column attached spirit to the base or the soil beneath the footing there are three main types of column footing the first one is, Spread Footing the second while Stepped footing and the third one is Sloped Footing.

Column Footing

ii. Strip Or Wall Footing:

Strip footings are typically observed in load bearing masonry construction, and act as long strip does guide the burden of an whole wall, strip footing is also furnished for a row of columns which is probably so cautiously spaced that their spread footings overlap or almost contact each In this kind of case, it's miles extra reasonable to provide a strip footing then to offer some spread footings in a single line. This type of Seville strip footing support them not coming from masonry or concrete wall transferred to the soil.

Strip Footing

iii. Combined footing:

When the two columns are so carefully every other that they may be individual footings might overlap. This is the first motive we use mixture for the second cause. A blended footing is also furnished while the assets line is so near one column that a spread footings could be eccentrically loaded when kept totally earlier in the property. By combining it with that of an indoors column, the Load is lightly distributed.

iv. Raft Foundation Or Mat Foundation:

This one is raft foundation, we use raft foundation when the allowable bearing capacity of soil is low in relation to the weight of building and column footings may become large enough that it's extra reasonably priced to merge them into a single mat that supports the whole building.

Raft Foundation

So we use it when the incapacity is low and it's more economical to merge all the combined order column footings.

2. Deep Foundation:

The Deep foundation penetrate through little upper layer of incompetent soil in order to transfer the load to switch the load to competent bearing soil or rocks deeper inside the earth.

Example of deep foundation is,

Caissons
Piles

i. Caissons

What is causing? It is just like column footing in that it spreads the load from a column over a massive sufficient area of soil that allowable stress within the soil isn't always exceeded. It differs from a Column footing in that it extends through strata of unsatisfactory soil below a substructure of Building till it reaches a more appropriate stratum.

Caisson

So this is the case if it penetrated through the stratum of soil until treat suitable stratum and there are two types of cases first one normal caisson and the second one named socketed caisson.

Caisson Construction:

So how we construct caisson? A constructed by way of the drilling or hand-digging a hollow, belling (flaring) the hollow out at the lowest as essential to reap the desired bearing area, and filling the hollow with concrete. Large auger drills are used for drilling caisson; hand excavation is used only if the soil is too full of Boulders for the drill.

Socketed Caisson:

A socketed caisson is drill into rock at the bottom rather than belled. Its bearing ability comes not only from its give up bearing, however from the frictional forces between the edges of the caisson and the rock as well.

ii. Piles:

Now we will talk about piles, piles are distinguished from caisson by being forcibly driven into the earth rather than that drilled and poured.

It may be used in which non-cohesive soil, subsurface water condition, or immoderate intensity of bearing Strata make caissons impractical.

Piles

Types Of Piles

There are two types of piles that drilled in the soil,

What is the difference between end bearing pile and friction pile,

End Bearing Pile	Friction Pile
· Its tip encounters organization resistance from an appropriate bearing stratum including rock, dense sand or gravels.	· It is driven simplest into softer material, without encountering a firm bearing layer, It may additionally still broaden a sizeable load-wearing via frictional resistance between the edges of the pile and the soil through which it.

Pile Driven Procedure:

We use pile hammers. Pile hammer is a large weight lifted by energy of steam, compressed air, compressed hydraulic fluid or a diesel explosion.

So we use this pile hammer to drive pile into the soil. In certain type of soil, pile can be driven more efficiently by vibration than by hammer blows alone, using a vibratory hammer mechanism.

Piles Driven Procedure

Piles Materials

There are three main types of piles according to their materials:

Wood Piles

Steel H Piles and Pipe Piles:

Third one is America's concluded by as you see in the mixture this one is H piles this one is a steel pipe pile this one is,

Precast Concrete Pile:

Piles Materials

Geotechnical Engineering:

You build a piece of infrastructure it has to be linked to the floor. Geotechnical engineering is about know-how the infrastructure interacts with the floor.

Geotechnical engineers cope with many kinds of infrastructure, tunnels, bridges, dams, buildings, roads, railways, port and landfills - which are constructed on the floor. The floor nearly usually has a complex behavior, whatever the sort of soil or rock it is made of, so geotechnical engineering is very exciting and challenging - no two issues are ever the same.

Geotechnical Engineering

Structural Engineering:

Analyzing and designing the construction of bridges, towers, buildings, dams and extra is the activity of a structural engineer. These systems need to construct in a way that makes them safe, sustainable, economical, and somewhat beautiful to the eye. Just like production and management engineering, structural engineering makes use of math and physics to do the activity. Using math and physics, engineers can see if all components of the assignment have enough energy to take loads, determine the systems' provider life, and notice if the shape is stable. Of 5 kinds of civil engineering projects, structural engineering plays the biggest component in designing and deciding on materials for a project.

Structural Engg

Transport Engineering:

To no surprise, transport engineering is the planning, designing, and operation of big transport systems.

We need a broad variety of constantly evolving, large-scale shipping infrastructure, together with road, rail, air and water. Transport engineers activity is to make sure these styles of transportation meet positive standards. Standards like sustainability and safety want to be met. With the era we've now, transport engineers try to lessen emissions and strength use with the goal of turning into environmentally friendly.

Transport engineering has constantly been certainly one of the vital civil engineering disciplines, impacting roadways, bridges, transit stations, airports and sea ports etc. Transport engineering has now developed right into a multidisciplinary subject spanning economics, politics, sociology and psychology, similarly to its center mathematical, engineering and computational principles.

Transport Engineering

Water Engineering:

How does water engage with our environment? Water engineering is about know-how why natural water structures which include rivers and coasts behave the way they do. Water engineering also includes designing approaches to shop or direct water. Understanding how water works can create a way for us to conserve water. Right now, water engineering is centered on handling floods, groundwater, and the character of coastal waters.

Water Engineering

Construction and Management Engineering:

Construction and control engineering is about creating things like bridges, buildings, roads, and railways. The cause of engineering construction is to build those structures inside the most efficient, safe, sustainable, and environmentally friendly manner possible. Following the construction phase is an asset management segment. In this phase, you outline the maintenance, operation, and refurbishment over the lifespan of the challenge. These things want to be controlled so that the owner of the task can make sure that there may be value in go back for money spent on the project.
