What is Precast, Prestressed Concrete? - Tindall Corporation

Both structural and architectural precast concrete may be prestressed or nonprestressed. Prestressed concrete may be achieved using either pretensioning or post-tensioning methods. With pretensioning methods, the strands are tensioned before placing the concrete and after the concrete has gained adequate strength, the tension is released with
