Concrete is a mixture of sand, gravel, cement, and water. Generally, you have 1 part cement, 2 parts sand, and 3 parts gravel. Sand makes up about 1/4 or 1/3 of a cubic foot.
concrete – cement (the binder), aggregates (ranging in size from fine to coarse) and water. Cement reacts with water to form hardened silicate compounds that bind all of the individual aggregate components together into one homogenous material – concrete. This reaction is known as hydration. In recent decades, intense
