What is Prestressed Concrete Blog Florida Engineering

Prestressed concrete is generally able to withstand cracks and is more cost effective for reinforcing large slabs of concrete. Because there is a lesser number of joints within the concrete, it cuts down on maintenance costs during the overall life of the building. There are three ways concrete is Prestressed: pre-tension, bonded post-tension ...
