Pemanfaatan Bottom Ash Sebagai Bahan Pengganti Pasir Dengan Mutu Beton 28 Mpa

Currently, a lot of coal fuel waste (bottom ash) is produced and dumped / piled up in industrial areas. Handling of coal fuel waste is still limited to stockpiling on vacant land. This is potentially dangerous for the environment and the surrounding community if it is carried into the waters. The point of view of waste coal fuel must be changed, that (bottom ash) is a potential raw material that can be used as a cheap adsorbent. The method used in this test is to make a concrete mixture using SNI 7656:2012 with Bottom Ash as a sand substitution material of 10%, 20%, 30%, and 40%. The concrete that was treated for 7 days, 14 days, and 28 days was then tested to get the compressive strength and density of the concrete. The purpose of this research is to use Bottom Ash as a sand substitute with the aim of getting the compressive strength value of each percentage addition of Bottom Ash, and to determine the effect of Bottom Ash on volume weight, to determine the effect of adding Bottom Ash to the slump test
