Prestressed Concrete - Portland Cement Association

Compressive Strength Added. Compressive stresses are induced in prestressed concrete either by pretensioning or post-tensioning the steel reinforcement. 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.
