Bottom Ash as Sand Filler Replacement in Concrete
As the world’s infrastructure develops, so does the need for concrete building materials. Malaysia is one of the nations that use pulverized coal to create power, and the burning of coal produces tons of bottom ash, which is considered industrial waste. Industrial waste disposal must be appropriately handled since it may influence the environment. Researchers have looked at the possibility of using this industrial waste as a component in concrete manufacturing to save natural resources. This work aims to investigate the characteristics of normal weight concrete using coal bottom ash (CBA) as a partial replacement for sand as fine aggregate. To make M30 grade concrete with a constant water-cement ratio, the replacement percentage of sand as fine aggregate with CBA utilized in this research project is 10, 20, 30, 40, and 50% by volume. The control concrete specimen was cast and tested with 100% sand as fine aggregate. There were 36 specimens cast and tested in total. The specimens were water cured for 7 and 28 days, following which their compressive strength was measured. Its workability and compressive strength test results were compared to standard concrete. CBA has shown encouraging results in compressive strength, solving the problem of industrial waste disposal, and preserving natural resources.
