Precast concrete is a type of construction material made with concrete cast in a reusable mould and cured in a controlled environment. Standard concrete is poured in place in large forms and cured on site.
Ancient Romans made use of concrete and poured the material into moulds to build their network of aqueducts, culverts and tunnels. Modern uses for precast concrete products include a variety of architectural applications including concrete retaining walls used for landscaping or earth retention, prestressed concrete panels, and concrete barriers. Precast architectural panels are also used to clad all or part of a building. Stormwater drainage, water and sewage pipes, and tunnels all make use of precast concrete units. The advantages of using precast concrete is the increased quality of the material, when formed in a controlled environment, and the reduced cost vesus casting on-site.
