Flexural Strength Flexural strength is an indirect measure of the tensile strength of concrete. Reference Standards. To determine the Flexural Strength of Concrete, which comes into play when a road slab with inadequate sub-grade support is subjected to wheel loads and / or there are volume changes due to temperature / shrinking.

FLEXURAL STRENGTH TEST OF CONCRETE Objective. It is a measure of the maximum stress on the tension face of an unreinforced concrete beam or slab at the point of failure in bending. It is measured by loading 150 x 150-mm (or (100 x 100-mm) concrete beams with a … depth.
of Civil Engineering, Thiagarajar College of Engineering, Madurai Copper slag is obtained as waste product from the sterlite industries, which produces copper in the form of cathode. The two standard methods used to test the flexural strength of any material are: ‘Third-point loading’ and/or ‘Center-point loading’.

The flexural strength is expressed as Modulus of Rupture (MR) in psi (MPa) and is determined by standard test methods ASTM C 78 (third-point load-ing) or ASTM C 293 (center-point loading).
The flexural strength for all the mixes was determined by test method I of the ASTM D 790M-93 (1998).The results of all the flexure tests are summarized in Table 3.2.The average modulus of rupture of the prepared mixes ranged from 10.4 to 21.2 MPa. The three-point bending flexural test provides values for the modulus of elasticity in bending, flexural stress, flexural strain and the flexural stress–strain response of the material. Test setup.
In the bending flexural test, a specimen is loaded under uniaxial bending stress (tension and compression) in order to obtain information on the bending behaviour of materials.Especially brittle materials such as hard metals, tool steels and grey cast iron are tested in flexural tests. IS: 516-1959 – Methods of tests for strength of concrete Flexural MR is about 10 to 20 percent of compressive strength depending on the type, size and volume of coarse aggregate used.
