Concrete is typically made of cement, water, sand, and aggregate (such as gravel, or crushed stone). These materials are mixed together to form a paste that hardens over time into a solid structure. The ratio and type of ingredients used can vary depending on the intended use of the concrete. The most common concrete mixture is made by blending ...

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.
