Aggregates make up most of the volume in concrete, but it is a mixture's cementitious materials that bind its aggregates together. Cements such as ordinary portland cement (OPC) and portland-limestone cement (PLC) react with water in a nonreversible chemical reaction called hydration to form strong, stiff, and impermeable hydrated cement paste.
