Flexural strength of m20 concrete
WebJun 28, 2024 · Cubes and beams are cast for M20 grade concrete with and without shredded plastics and tests on concrete are conducted. The standard mechanical properties of concrete like compressive strength, flexura land strength are tested and compared with the results of standard specimen. WebDec 8, 2024 · Empirical Formula for Estimating Flexural Strength of Concrete. As per IS 456 2000, the flexural strength of the concrete can be computed by the characteristic compressive strength of the concrete. Flexural strength of concrete = 0.7 sqrt ( fck) Where, fck is the characteristic compressive strength of concrete in MPa.
