Compromising with the concrete quality is one of the reasons for crack developments in reinforced concrete slabs. Poor concrete quality results in lower concrete strength, specifically, the tensile strength. As a result, the tensile strength of concrete reaches its maximum limit at a very low magnitude of stress.
