The Effect of Coal Bottom Ash Powder Particle Size on The Physical and Mechanical Properties of Composites Polyester Matrix
Abstract
Bottom ash is formed from inside the boiler furnace in the form of solids not carried by the flue gas. In CFB systems, bottom ash is between coal ash, quartz sand and fragments of the furnace wall that are eroded during the combustion process. Composite materials made from bottom ash fillers were made using variations in bottom ash powder size, namely 200 mesh and 300 mesh with a weight fraction between epoxy resin and bottom ash powder, 10% volume of bottom ash powder vs 90% volume of resin; 20% volume of bottom ash vs 80% volume of resin; and 30% volume of bottom ash vs 70% volume of resin. This research uses 2 tests, namely, tensile testing and water absorption testing. The results showed that the specimen with the maximum tensile strength and strain values was found in the 200 mesh grain size specimen with a composition of 30% bottom ash powder volume vs. 70% resin volume, which amounted to 28.1 Mpa and 3.9%. While the minimum water absorption is found in the 200 mesh size specimen with a water absorption of 0.003%.
