Contrary to popular belief, concrete and cement are not the same thing; cement is actually just a component of concrete.Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement.Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or concrete mix, will be poured and harden into the durable material with which we are all familiar.. The concrete mix is workable. It can be placed and consolidated properly by yourself or your workmen. 2. Desired qualities of the hardened concrete are met: for example, resistance to freezing and thawing and deicing chemicals, watertightness (low permeability) , wear resistance, and strength.
