Cracks and Crack Control in Concrete Structures - PCI
www.pci.orgConcrete can crack due to a number of causes. Some of the most significant causes are discussed in detail. Tensile Strength of Concrete The tensile strength of concrete is a widely scattering quantity. Cracking oc-curs when tensile stresses exceed the tensile strength of concrete. Therefore, to control concrete cracking, the tensile
Post-Tensioned Concrete in Residential Construction

This bending creates high tensile forces that can cause the concrete and masonry to crack.
