Evaluation of Young's Modulus of SFRC Members

Prashant C. Hargude | Suresh R. Parekar

Abstract: The modulus of elasticity of concrete is a very important parameter reflecting the ability of concrete to deform elastically. The aim of study is to verify the influence of steel fibers on the modulus of elasticity of reinforced concrete members. Study carries casting and testing of 12 cube specimens, 3 specimens of RCC and 6 specimens of SFRC beams. The concrete grade considered for study is M30. In the experimental study the concrete mix has been design as per the guidelines given in IS 10262-1982 published by Bureau of Indian Standards. In SFRC cube specimens, volume fraction (Vf) of steel fiber varies from 0.5 % to 1.5 % at an increment of 0.5 %. The volume fraction of steel fiber used for beam specimen is 1.5 %. The aspect ratio of steel fiber is 65 and 80. The size of cubes and beams are 150 mm 150 mm 150 mm and 150 mm 150 mm 700 mm respectively as per IS 516-1959. The value of modulus of elasticity (Eb) will be evaluated from the load vs. deflection curve of beam specimens.
