Abstract

Fiber reinforced concrete(FRC) has indisputable applications in civil engineering. FRC has so far successfully used in slabs, precast products, crash barriers, footing and structures in seismic regions. FRC is gaining attention as an effective way to improve the performance of concrete, the applications are becoming popular and are exhibiting excellent. Recycled aggregates in concrete opens new range of possibilities in reuse of material in building industry. This reduce excess waste material and cost. This study provides the performance of fiber reinforced concrete with recycled aggregate. In this project coarse aggregate is replaced with recycled aggregate about 20% by weight of coarse aggregate itself these tests are carried out to a design mixed of M70 grade and are compressed strength for 7 to 28days In this project cement is replaced with ALLCOFINE&GGBS about 5% and 25%respectivtly,coarse aggregate replaced with 20% of recycled aggregate. Steel fibre is added at different preposition that is 0.8%,1%,1.2%,1.4% by weight of cement, the performance of frc is carried out for M70 grade mix design at different trails.
