Today’s modernization and rapid industrialization has resulted in construction of several wonderful structures, with reinforced cement concrete as the most prominent construction material. Earlier it was assumed that concrete is a very durable, maintenance-free material. But time and again, the experience has proved us wrong and there is definitely a maintenance requirement for all concrete

CAUSES AND PREVENTION OF CRACKS IN BUILDING

noreply@blogger.com (The Civil Engineer) — Tue, 26 Nov 2019 21:25:00 +0530

A crack is a complete or incomplete separation of concrete into two or more parts, produced by breaking or fracturing. The crack in concrete is an inherent feature, which cannot be completely prevented but can only be controlled and minimized. Concrete being a material having very low tensile strength, readily cracks when such

ACTIVE AND PASSIVE CONTROL SYSTEMS CONSIDERING EARTH QUAKE EXCITATION

noreply@blogger.com (The Civil Engineer) — Sun, 24 Nov 2019 23:16:00 +0530

The energy imparted to a structure from earth quakes is dissipated by damping, if the earth quake is large enough; it is accompanied by plastic yielding. The damping energy is associated with inherent structural damping of the conventional members, and the external damping contributed by the structural control systems, such as viscoelastic (VE) damper and active

DURABILITY OF CONCRETE STRUCTURES

noreply@blogger.com (The Civil Engineer) — Mon, 4 Jun 2018 21:21:00 +0530

During the recent past, the problem of early deterioration of concrete structures has assumed serious proportion all over the world. In India also, this problem is being witnessed in the past few years, especially in coastal and industrial belts as well as in other aggressive environments. Durable concrete can be defined as one that is designed, constructed and maintained to perform

Waterproofing in Construction Industry

noreply@blogger.com (The Civil Engineer) — Wed, 10 Apr 2013 06:26:00 +0530

In building construction, a structure needs waterproofing since concrete itself will not be watertight on its own (but note concrete is easily waterproofed with additives). The conventional system of waterproofing involves 'membranes'. This relies on the application of one or more layers of membrane (available in various materials: e.g.,

BRICKS

noreply@blogger.com (The Civil Engineer) — Wed, 10 Apr 2013 00:16:00 +0530

Bricks are one of the oldest types of building blocks. They are an ideal building material because they are relatively cheap to make, very durable, and require little maintenance. Bricks are usually made of kiln-baked mixtures of clay. In ancient times, bricks were made of mud and dried in the sun; modern bricks are made from concrete,
