Dec 14, 2021· Cement is a powder made of a variety of materials (usually certain types of clay and limestone). When cement is mixed with water a chemical reaction called hydration occurs that causes the cement to harden. Aggregate is a mixture of fine and coarse aggregates. The fine aggregate is typically sand; the coarse aggregate is typically gravel rock.
