Cement & Concrete FAQ
Portland cement and portland-limestone cement are the most common types of cement used in concrete. In concrete, a paste made of cement and water is mixed with aggregates (sand, gravel, or crushed stone). As the cement reacts chemically with the water, it binds the aggregates into a rock-like mass. Concrete continues to harden and gain strength ...
