Seriously loaded concrete floor slabs and pavements is usually sensitive to cracking and subsequent targeted visitors-pushed deterioration. Subsequently, prestressed concrete is often Utilized in this sort of structures as its pre-compression provides the concrete with the chance to resist the crack-inducing tensile stresses produced by in-assistance loading.
