Cement and additions

Cement will hydrate under water. If there is an inadequate amounts of water available hydration will stop and the concrete may be of poor quality. The process of keeping water in concrete to facilitate full hydration is known as curing. Until recently, the term ´cement´ was an abbreviation for Portland cement.

What is Fly Ash?

Fly ash is a byproduct from burning pulverized coal in electric power generating plants. During combustion, mineral impurities in the coal fuse in suspension and float out of the combustion chamber with the exhaust gases. As the fused material rises, it c
