A study of fine aggregate replacement with fly ash an

Sand was replaced with 10% to 50% of fly ash by weight and 0.5, 0.55, 0.6 and 0.65 W/C ratios were used. Flow test performed for mortar revealed that as the percentage replacement of sand with the fly ash increased the flow of the mortar decreased. It was also observed that wet and dry densities were more than the control mortar for 10% & 20%

Feasibility Study of Fly Ash as a Replacement for Fine

replacement of natural sand by fly ash is about 30% as compared to reference mix (0% replacement). 3. It is observed that the residual tensile strength of concrete when subjected to elevated temperature of 200°C for 4 hours, is higher at 40% replacement of natural sand by fly ash. After 40% replacement the tensile strength decreases.
