s steel bars installed on the bottom, which allows it to hold tension. Concrete is durable enough to withstand the rigors of heavy load. Prestressing eliminates design limitations experienced by normal concrete. It can be used for constructions that require massive spans without support, for example, floor, walls, roofs as well as bridges. Concrete that is prestressed is typically used in commercial spaces such as shopping malls cafeterias, parking spaces, and auditoriums for schools.

The concrete that has been stretched can be created using two ways. Pre-tensioning is one of the methods. It requires stretching steel in the beginning before the concrete is set in the concrete. The process is carried out in factories, and the ready concrete is transported via trucks to the construction site. Another method is post-tensioning, where the concrete is allowed to get harder before it is stretched. Concrete can then be used immediately after it has cooled. Concrete of this type can be used in a vast number of construction tasks that can bear intense loads without fear of injury.
