Energy In Concrete Processes

Concrete is a hardened building material created by combining a chemically inert mineral aggregate usually sand, gravel, or crushed stone, a binder natural or synthetic cement, chemical additives, and water.Although people commonly use the word cement as a synonym for concrete, the terms in fact denote different substances cement, which encompasses a wide variety of fine-ground powders.
