Abstract
Concrete is a brittle material when subjected to normal stresses and impact loads, where tensile strength is relatively low compared to compressive strength. This can be improved by addition of fibrous material. The geometric size and modulus of fibers are the main factors influence the mechanical performance of fiber reinforced concrete. The use of different type of fibers in a suitable combination may potentially improve the overall mechanical performance of concrete and increase tensile strength, energy absorption capacity of concrete. The present investigation studies the synergic mechanical properties of hybrid fiber polymer reinforced concrete. The properties of plain concrete, mono steel fiber concrete, glass fiber concrete and hybrid fiber concrete of M20 grade were studied and the properties of hybrid fiber concrete are compared with respect to plain and mono steel fiber and glass fiber concrete. Similarly the axial stress-strain curves under Axial Compression are studied.
