Flexural Strength (Modulus of Rupture) of concrete is the theoretical maximum tensile stress reached in the bottom fibre of a test beam during a flexural strength test [1]. It is one of the important parameters for computing deflection in reinforced concrete structures [2]. Flexural strength is an input in the design of rigid pavements.
