Portland Cement is a commercial grade cement that can handle any number of1 Portland Cement Concrete Pavement - in.gov,Concrete basically consists of Portland cement, water, and fine and coarse aggregates. The curing of the concrete is a chemical reaction of the Portland cement and water, which causes the concrete to shrink and crack. To control the cracking, transverse joints and longitudinal joints are constructedCement & Concrete Applications,In its simplest form, concrete is a mixture of paste and aggregates. The paste, composed of portland cement and water, coats the surface of the fine and coarse aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
