Concrete is one of the most used construction material in the world. Earlier the usage of conventional concrete was more, but now-a-days the concrete is experimented with the implementation of various different materials into it which is both natural and artificial materials, like partial replacement of cement with admixtures which makes the concrete mix more economical as the reduction in the cement content will be achieved with increase in the strength and is also eco-friendly. Fibres are also implemented in concrete which serves as a good reinforcement property to the structural element and makes it a good tension member. In this study, cement is replaced with 20% fly ash which is an industrial by-product and implementation of basalt fibre and polypropylene fibre is done in 0.3%, 0.6% and 0.9% variations for which the fresh and hardened concrete properties and the cost feasibility are also checked and compared with the values of conventional concrete. This study is carried out for M25 grade concrete with 0.4 water cement ratio.
