Posttensioned Concrete Slab-on-ground Foundation

What does a posttensioned concrete slab-on-ground foundation generally consist of? A posttensioned concrete slab-on-ground foundation generally consists of a single concrete slab.

Explanation:

A posttensioned (PT) concrete slab-on-ground foundation generally consists of a single concrete slab. Posttensioning is a technique used in concrete construction to improve the performance of concrete slabs. After the concrete slab is poured and cured, steel strands are threaded through the slab and then tensioned. The tension compresses the concrete, improving its resistance to bending and cracking, making it more durable and capable of supporting larger loads. Hence, a PT concrete slab-on-ground foundation does not usually require multiple layers of concrete, wooden beams, or a metal framework.
