abstract application of recycled materials in the building industry is essential for permanently sustainable development of each country. the use of primary sources and materials is becoming unbearable both economically and ecologically, and therefore it is necessary to seek the possibility of reuse of those materials once their durability expired this project deals with the comparative study of flexural behavior of fibre reinforced concrete using recycled aggregates with quarry dust replacement. for reducing cost of concrete and also to meet the demand, locally available waste materials such as quarry dust and recycled materials have been utilized in concrete. the aim of this project is to study enhancement of flexural strength, splitting tensile strength and modulus of elasticity due to the addition of polypropylene fibres and recycled aggregates in concrete and the replacement of crusher dust in concrete. the compressive strength of concrete reaches the maximum value at a replacement level of 0.5% of fibers and same behavior is observed while replacing completely with recycled aggregates and quarry dust. the split tensile strength of concrete reaches the maximum value at a replacement level of 0.5% of fibers and same behavior is observed while replacing completely with recycled aggregates and quarry dust the flexural strength of concrete beams attains max value of 54kn ultimate load at a replacement level of 0.5% of fibers. the load deflection behavior shows a ductile behavior at 0.5% of fiber replacement level. the stiffness and energy absorption capacity at ultimate load are more in the 0.5% of fibre proportion. hence it is concluded that recycled building waste can be effectively used as a fully replacement for natural aggregate.
