2016-9-9 · 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.
