Abstract :Now a days light weight aggregate concrete gained more importance than the normal conventional concrete due to its lesser density and high thermal conductivity. Glass fibre reinforced concrete is a composite material used to reduce the brittleness and increases ductility. Increasing utilization of light weight materials in structural applications is making pumice stone a very popular material. The addition of glass fibre to the light weight aggregate concrete gives better results than light weight concrete. In the present study coarse aggregate is replaced by pumice stone with 5%, 10%, 15%, and 20% along with optimum percentage (5%) of fly ash which is a replacement of cement. The optimum value obtained from these is considered and added with optimum percentage (1.5%) of glass fiber. The test results show that the density of light weight concrete decreases as increase in the percentage replacement by pumice stone. Compressive strength, split tensile strength and flexural strength results shows that the pumice stone replacement with 5% is the optimum value. Addition of glass fibre to the optimum mix shows that compressive strength, split tensile strength and flexural strength are increased by 14%, 17.5% and 19% respectively.
