Compressive and Tensile Strength of Concrete: Relation

The flexural strength of concrete was found to be 8 to 11% of the compressive strength of concrete of higher strength concrete of the order of 25 MPa (250 kg/cm 2) and 9 to 12.8% for concrete of strength less than 25 MPa (250 kg/cm 2) see Table 13.1: . The ratio of flexural strength to compressive strength was found higher for 40 mm maximum size aggregate than that of 20 mm max sized aggregate.
