What is concrete concrete is the final product resulting from mixing cement, aggregates including sand, water, and mixtures.It is initially malleable in its wet state and solidifies over time, gaining strength and durability.The first use of concrete was by the roman empire.Although there is some indication that earlier civilizations used a distant.
