Most commonly, regular concrete is created by mixing Portland cement with both an aggregate and water-chemical mixtures. Often times, cement and concrete are incorrectly interchanged: concrete is the hard, rock-like substance that is so frequently seen in urbanized areas. Cement is an ingredient, the powder, used in the creation of concrete.
