Prestressed Concrete is an architectural and structural
material possessing great strength. The
unique Characteristics of
prestressed concrete allow predetermined, engineering stresses to be placed in
members To counteract stresses that
when the unit is subjected to service loads. This is accomplished
by Combining the th best properties of two quality materials:
high strength concrete for compression and
high Tensile strength steel strands for tension.
Actually, prestressing is quite simple.
strands are stretched between abutments at each end of Long casting beds.
- Low Maintenance, Long Life
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.
