Prestressed Concrete (Yard Operations) - National Safety Council
There are two basic methods of prestressing concrete—pretensioning and post-tensioning. This data sheet is limited to the pretensioning method. 5. In pretensioning, the wire strands or bars are tensioned before the concrete is poured. After the concrete has cured, the load is removed from end abutments and transferred by strand
