Concrete Paving - Indiana

Concrete basically consists of Portland cement, water, and fine and coarse aggregates. A pozzolan material, such as fly ash, may be added to the concrete mix as a partial substitute for cement. The curing of the concrete is a chemical reaction of the Portland cement and water, which causes the concrete to shrink and crack.
