Abstract
The concept and usage of Fibre reinforced concrete gained more recognition and has also proved to result in greater tensile strength. The concrete, which contains fibrous materials are called fibre reinforced concrete. Glass fibre reinforced concrete (GFRC) is a material made of cementitious compounds consists of cement, aggregates, water, admixtures and discrete fibres. The performance of different grades of concrete such as M25, M30, M35 with addition of various percentage of glass fibre such as 0.2%, 0.4%, 0.6%, 0.8%, 1% with different W/c ratio are used to maintain the high workability. The tensile property of various mixes of glass fibre reinforced concrete is compared with conventional concrete at the age of 7 days and 28 days. The optimum value fibre percentage in different grades of concrete is 0.6%.
