Most Concretes produced today contain materials in addition to Portland cement to help achieve the strength or durability performance. These materials include fly ash, silica fume and ground-granulated blast furnace slag used separately or in combination. In this project we used phosphogypsum as admixture to improve the performance of concrete. It is a waste material obtained from fertilizer manufacturing. Also, steel fiber is introduced to increase the tensile strength of concrete. The grade of concrete used is M20 & M25. For both the mixes, phosphogypsum is added as 0%,15%, 20% & 25%. The steel fiber is kept constant for all the mixes as 50kg/m3. The material testing’s done to arrive the mix proportion. The fresh concrete properties are studied. Harden concrete properties of concrete like compressive strength, split tensile strength are done and the results are enclosed in this report. It was found that the concrete with 15% phosphogypsum & 50kg/m3 shown good performance both in fresh and harden state.
