Majority of the country's energy supply relies on thermal power plants, mainly coal-fired powered plants. Due to problems in disposal and the rapid production of bottom ash, environmental issues arise. A great potential for the utilization of bottom ash can be applied in the civil engineering industry, noted to be promising in the material science industry. Therefore, one way to remedy the concern is to utilize bottom ash by partially replacing sand as fine aggregates in a concrete mix. The proposed research intends to promote the usage of bottom ash by attaining the performance of the coal by-product when mixed in concrete. Two testing methods were considered destructive and non-destructive methods namely compressive strength test and maturity meter test respectively. The strength of all the samples increased and at 40% bottom ash replacement the workability became a dilemma therefore super plasticizer was necessary. The strength of the samples were compared and discussed throughout the results.
