3 5 this compression is produced by the tensioning of high strength tendons located within or adjacent to the concrete and is done to improve the performance of the concrete in service.
The reduced weight also lowers material and transportation costs.
Concrete is a composite material consisting mainly of portland cement water and aggregate gravel sand or rock.
Precast concrete is a construction product produced by casting concrete in a reusable mold or form which is then cured in a controlled environment transported to the construction site and lifted into place tilt up.
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement cement paste that hardens cures over time.

Precast concrete elements can be joined to other elements to form a complete structure.
This makes the slab much lighter than a massive solid concrete floor slab of equal thickness or strength.
It is substantially prestressed during production in a manner that strengthens it against tensile forces which will exist when in service.
Precast concrete is a form of concrete that is prepared cast and cured off site usually in a controlled factory environment using reusable moulds.
