  • Compressive and Tensile Strength of Concrete: Relation

    On the basis of test data of the study, CRRI has sug­gested the following relation between flexural strength and compressive strength of concrete: y = 11 x – 3.4 . where y is the compressive strength of concrete in MPa and x its flexural strength. This relation depends on the size of coarse aggregate.
