Eight months after concrete was poured, the top eighth inch is flaking off, in a lot of different places. There are a lot of spots you can see that are loose and will flak off.

Can you tell me what could have caused this problem, Also I would like to know if a topping of some kind can be used, If so what kind of

topping would be best, And how to prepare surface before appling a topping. My contractor tells me he is going to fix it, But he dose not seem to know just what to do.

THANKS FOR ANY ADVICE YOU CAN GIVE

My name is Ron Maloney. I work for a government department in Australia (Roads and Traffic Authority).My branch delivers new roads and bridges to the state.

The question Is what do you think of redosing of high strength concrete ?.

The concrete has had the water reducer added at the plant and hauled for approx. 1 hour. The slump is reverting, and is to old to retamper. The contractor would like to redose to improve the slump. What do you think?

28″ X 28″ X 3″ . Am using a wheel barrel to mix it in however, don’t know when to stop mixing , that is, using the water of course?

Please help me….am new to this, hard breaking back work and sweatty type of work, but it has to be done.

Also pouring cement in between 2″ X 3″ (measure above).

Counted about 15 squares of 28X28X3 and I figure about 75 sacks of premix cement…Am I way off?

Thank you,

John

i have been working with mortars mixed with lime and different aggregates tocome up bwith my own decorative mortars

lately since I work in dry and hot conditions i have problems with the mixture

it still dries the way Iexpect it to dry

but it has no more strenght

it seems to me that the water that i am adding is evaporating to quickly so it does not allow to make a strong bond

I have understood that lime by itself holds water longer in the mixture and works as a natural plastifier

wood there be any agent available that could help me with this problem still keeping the lime in the mix

I have looked into acrylic polymers but it seems to me that they are reducing the water ratio

I hope you have the answer for my problem

regards

lara
