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.

The utilization of fly ash as sand partial replacement in concrete mix is an alternative solution for the depletion of sand resources in the Special Region of Yogyakarta. This research evaluates the effect of sand partial replacement with fly ash to the strength-weight and cost-strength ratio of concrete mixes. The strength-weight ratio was used for mechanical evaluation with higher value ...

The use of fly ash as replacement of sand is an economical solution for making green and denser concrete. The paper presents a concrete mix design procedure for partial replacement of sand with fly ash. Present method could produce additional compressive and flexural strength for concrete with partial replacement of sand with fly ash over control concrete, with higher slump.
