Cement in construction has become a vital requirement to build up the buildings, which may increase the expenses in construction. Materials that have the potential to replace cement would be proposing. This study used municipal solid waste incineration bottom ash (MSWIBA) as a partial replacement for cement. MSWIBA used in this study was a by-product from the incineration process and had compound content that was almost the same as cement. The treated bottom ash in the range of 0 to 30% and 10% of untreated bottom ash mixture use in this study. Mechanical and physical properties of concrete analysed with a few tests such as slump test, water absorption test, compressive strength test, heat exposure test and residual strength test after heating has proceeded. The workability of fresh concrete was measured by performing a slump test. Based on the compressive strength result, the 10% substitution of treated bottom ash was achieved the highest strength in testing in 7 and 28 days. Meantime, the control concrete obtained the best thermal insulator because of a smaller number of cracks on the surface of the concrete than that bottom ash concrete surface. After heated, the concrete was tested on compressive strength again to investigate the residual compressive strength. The highest residual surpasses gained by 10% bottom ash (treated) as a partial substitution in cement. Based on the overall test carried out, 10% of bottom ash replacement as cement is the optimum amount of bottom ash required to surpass the strength of the control sample.
