Cracks and Crack Control in Concrete Structures

Cracks and Crack Control in Concrete Structures

+

Concrete 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 stering quantity. Cracking occurs when tensile stresses exceed the tensile strength of concrete. Therefore, to control concrete cracking, the tensile
