In this blog, what is prestressed concrete is explained in simple words.
Prestressed concrete is also a special type of concrete. As we are aware of the fact that concrete is good in compression and weak in tension. We stress the concrete in the production stage itself by compressing the concrete so as to enhance the tensile properties of concrete. 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. Tendons may consist of single wires, multi-wire strands or thread bars that are most commonly made from high tensile steels.

Prestressed concrete is used in a wide range of building and civil structures where its improved performance can allow for longer spans, reduced structural thickness, and material savings compared with simple RCC.
