Prestressed Concrete Bridges

Types of prestressed concrete . Prestressed concrete is created through one of two processes: post-tensioning and pretensioning. Post-tensioning. The simplest type of early prestressed-concrete beams used steel cables to tightly tie together a row of concrete blocks end to end. This is like lifting a row of books by pressing them together from ...

Prestressed concrete - Wikipedia

Post-tensioned concrete is a variant of prestressed concrete where the tendons are tensioned after the surrounding concrete structure has been cast. The tendons are not placed in direct contact with the concrete, but are encapsulated within a protective sleeve or duct which is either cast into the concrete structure or placed adjacent to it. At each end of a tendon is an anchorage assembly firmly fixed to the surrounding co
