Prestressed versus
Other Materials
|
Prestressing
places engineered stresses in structual units -- stresses which more than
offset the stresses that occur when the unit is subjected to loads. We
accomplish this by combining two quality materials: high-strength concrete
and high-tensil steel.
High-tensil steel
strands are stretched between abutments. Concrete is then placed into
the forms which encase the strands. As the concrete sets, it bonds to
the tensioned steel. When the concrete reaches a specified strength, the
tensioned strands are released. This prestresses the concrete, putting
it under compression and creating a built-in resistance to loads which
produce stress.
