Prestressed concrete is one of the greatest innovations in modern civil engineering. It overcomes the limitations of ordinary reinforced concrete (RCC) and allows engineers to design longer, thinner, and more durable structural members.
Prestressed concrete is a form of concrete used in construction that has internal stresses induced to resist external applied loads. This post provides a comprehensive guide to prestressed concrete, covering its definition, advantages, disadvantages, methods, applications, and design.

Prestressed concrete is a form of concrete used in construction. It is substantially prestressed (compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. [1][2]: 3–5 [3] It was patented by Eugène Freyssinet in 1928. [4] This compression is produced by the tensioning of high-strength tendons located within or adjacent to the ...
As well as high compressive strength offers higher resistance to tension and shear and so it is desirable for prestressed concrete. Moreover, high-strength concrete is less subjected to shrinkage cracks.
As the name indicates prestressed concrete is a form of concrete in which internal stresses are introduced before its application.
