Define Prestressed Concrete
Concrete can handle a good amount of compressive stress but it does not have high tensile strength and that’s why concrete gets cracks when it has to deal with maximum load. As the name suggests, prestressed concrete is a concrete form in which internal stresses are introduced before its application to allow it to counter the tensile stresses produced in concrete due to external loads. Now you know what is prestressed concrete.

Pros of Prestressing Concrete
The prestressing of concrete by using high-tensile steel improves the materials’ efficiency.
This system of prestressing works for a span of more than 35 meters.
Prestressing enhances fatigue resistance and shear strength of concrete
Dense concrete offered by prestressing systems ensures excellent durability
It is perfect for use in the construction of slender and sleek structures.
Prestressing significantly reduces the concrete structure’s dead load
Prestressed concrete stays uncracked even in service load environments which ensures the structural efficiency
A compressive prestressing force can be applied eccentrically or concentrically in the member’s longitudinal direction. This helps prevent cracks at critical midspan and helps support service load.
Cons of Prestressed Concrete
Prestressing is an added cost
Higher material costs
Its formwork is more complicated than RC
