Post-Tension Basics- How Post - The Concrete Network

A residential post-tensioned concrete slab will typically be 8 inches thick and use 3000 psi concrete. Once the concrete has gained strength to 2000 psi, typically within the 3 to 10 days recommended by PTI, the tendons are stressed. Tendons today are seven high-strength steel wires wound together and placed inside a plastic duct.

Types of Concrete & Characteristics | Concrete Classifiion

The concrete is placed on the surface to be covered, and is compacted in place using large heavy rollers typically used in earthwork. In this type of concrete, the mix achieves a high density and cures over time into a strong monolithic block. Roller compacted concrete is typically used for concrete pavement.
