Experimental Study on Enhancement in Modulus of Elasticity of Concrete with Inclusion of Hybrid Fiber Reinforcement

Abstract
This article provides the experimental result in enhancement of modulus of elasticity of concrete by inclusion of
discrete fibers. Researchers have successfully demonstrated that the addition of fibers to concrete strengthens the
concrete by fostering interactions between the fibers and matrix. Concrete's elastic modulus, which affects the
stiffness of the material and is a reliable measure of strength, must be taken into consideration in order to maintain
the material's maximum serviceability. The tests on M20 and M25 grade conventional and Hybrid Fiber Reinforced
Concrete (HFRC) are carried out in laboratory to examine the improvement in modulus of elasticity. The
combination of hooked end steel fiber ranging from 0.5% to 1.00% by volume of concrete and fibrillated
polypropylene (PP) fibers from 0.3% and 0.6% is added in concrete.The study reveals that the addition of 1.00%
hooked end steel fibers + 0.3% fibrillated polypropylene fibers by volume of concrete significantly improves the
HFRC's experimental modulus of elasticity by 52.23% and 55.60% for M20 and M25 concrete respectively and also
helps prevent excessive deformation by avoiding the most cost-effective designs
