Cast-in-place concrete

Cast-in-place concrete, also known as poured-in-place, is a concreting technique which is undertaken in situ or in the concrete component’s finished position. Cast-in-place concrete is the preferred choice for concrete slabs and foundations, as well as components such as beams, columns, walls, roofs, and so on.

The concrete is typically transported to site in an unhardened state, often using a ready mixed concrete truck. A chute extends from the back of the truck to place the concrete either in the required location or into a dumper or pump.

An alternative concreting technique is precast concrete which is prepared, cast and cured off-site, usually in a controlled factory environment, using reusable moulds. For more information, see Precast concrete.

While cast-in-place concrete can allow for greater flexibility and adaptability, it can be difficult to control the mix particularly if weather conditions are not favourable. Cast-in-place concrete will also require a strength test and time for curing, which makes it slower to construct than precast concrete. However, there are fewer joints in the structural system not as much handling equipment is required.
