EXPERIMENTAL STUDY ON THE BEHAVIOUR OF TORSION IN GEOPOLYMER CONCRETE BEAMS WITH STEEL FIBERS

Abstract

Geopolymer concrete is new emerging trend of concrete which is an alternative for Ordinary Portland Cement (OPC). This alumino-silica binder in geopolymer concrete provides high resistance to chemical attack, elimination of water curing, rapid strength gain, and is an Ecofriendly material. Comparative study is carried out between geopolymer and conventional concrete and evaluated in terms of torsion. In this experiment research, four geopolymer beams and four conventional concrete beams with and without fibers have been casted and tested. This study carries out the comparison of conventional concrete and geopolymer concrete precracking, post-cracking behavior and torsional resistance. The ultimate torque resistance of geopolymer concrete is higher than conventional concrete. It is found that steel fibers volume of 1% increases torsional strength and prevents sudden brittle failure. It shows cracking torsional resistanceof geopolymer concrete (GPC) steel fiber beams are higher than conventional beam.
