Acoustic Properties of Lightweight Foamed Concrete with Eggshell Waste as Partial Cement Replacement Material

Nowadays, almost every industry needs to undergo green and sustainable industrial revolution due pollutions like waste dumping noise that deteriorating the environment. Therefore, feasibility study on application of eggshell as partial cement replacement in lightweight foamed concrete was conducted by aiming solve environmental acoustical issues, i.e. reduce improve acoustic properties. In this study, compressive strength properties 1300 kg m-3 with without 5% powder material were tested. Optimal water ratio 0.6 obtained for test comparing result. The result shows has generally reduced 7 days but improved 28 strength, either or maintain acoustics properties, which containing reduction coefficient at testing ages 7, 28, 90 sound transmission class age 56 days. Based these results, is feasible be incorporated into insulation development purposes.
