What is Concrete?

Concrete & Cement Information

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.

Following is a group of articles that will be helpful when trying to understand more about concrete and cement. Topics include issues relating to concrete basics, mix design, installation, and decorative concrete.
