Concrete is one of the worlds most used and strongest material. Concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates.
Once the concrete has been placed, the decorative aggregate is ready to be revealed. There are several exposure methods contractors can choose from, depending on the look desired and size of the project.
Portland Cement and Supplementary Cementitious Materials. Although it comprises between only 7 to 15 percent of the absolute volume of concrete mixture, it is the hardened paste that is formed by hydration of the cement upon the addition of water that binds the aggregate particles together to form a stonelike mass.
