Cement & Concrete Basics FAQs

Concrete is a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Cement comprises from 10 to 15 percent of the concrete mix, by volume. Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass.Ready Mixed Concrete - Portland Cement AssociationReady mixed refers to concrete that is batched for delivery from a central plant instead of being mixed on the job site.
