Precast concrete is an ancient type of construction material made with concrete cast in a reusable mold or "form" and cured in a controlled environment, then transported to the construction site and lifted into place. In contrast, standard concrete is poured-in-place in large forms and cured on site. Precast "stone" is distinguished from precast concrete by using a fine aggregate in the mixture so the final product approaches the appearance of naturally occurring rock or stone.
