Jan 10, 2021 · The effects of all features on compressive and flexural strengths are as follows: 2.1.1. W/C Ratio. A W/C ratio has a great influence on the strengths of concrete. Abbass et al. reported that both the compressive and flexural strengths decrease as the W/CHow to calculate flexural tensile strength?So to calculate the flexural strength (), multiply the force by the length of the sample, and then multiply this by three. Then multiply the depth of the sample by itself (i.e., square it), multiply the result by the width of the sample and then multiply this by two. Finally, divide the first result by the second.See all results for this questionFlexural Strength of ConcreteIt is measured by loading unreinforced 150x150 mm concrete beams with a span three times the depth (usually 450mm).
