Prestressed Concrete, its Concept, and Methods – Civilmint

Prestressed Concrete, its Concept, and Methods. Prestressed concrete is a system into which internal stresses are intentionally induced without any form of external loads to improve its performance. The internal stresses induced in the concrete structure is used to counteract the stresses originating from the external load application.

Prestressed Concrete - Definition and Methods of Pre-Stressing

Nov 21, 2017  Prestressed Concrete Definition. A creation of internal stresses in a structure in order to improve its performance. Such stresses are designed to counter-act stresses induced by external loads. Concrete is strong and ductile in compression, it is weak and brittle in tension, and hence its response to external loads is improved by pre-compression.

Prestressed concrete - Wikipedia

Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service.: 3–5 This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service.
