Prestressed Concrete
In pretensioning, the steel is stretched before the concrete is placed. High-strength steel tendons are placed between two abutments and stretched to 70 to 80 percent of their ultimate strength. Concrete is poured into molds around the tendons and allowed to cure. Once the concrete reaches the required strength, the stretching forces are released.
What is Prestressed Concrete and How Does It Work? | eSUB
The compressive stresses that give prestressed concrete its stability are generally introduced in one of two ways: pre-tensioning or post-tensioning. When using pre-tensioning, steel is stretched out before the placing of the concrete. This entails steel tendons set between two abutments, then getting stretched to roughly 80% of their strength.
