Pre-stressed
concrete is an architectural and structural material possessing
great strength. The unique characteristics of pre-stressed concrete
allow predetermined, engineering stresses to be placed in members
to counteract stresses that occur when the unit is subjected to
service loads. This is accomplished by combining the best
properties of two quality materials: high strength concrete for
compression and high tensile strength steel strands for
tension.
Actually, pre-stressing is quite simple. High tensile strands are
stretched between abutments at each end of long casting beds.
Concrete is then poured into the forms encasing the strands. As the
concrete sets, it bonds to the tensioned steel. When the concrete
reaches a specific strength, the strands are released from the
abutments. This compresses the concrete, arches the member and
creates a built in resistance to service
loads.
