摘要: The present study aims to determine and evaluate the applicability of a new product consisting coal bottom ash mixed with Portland cement in application highway noise barriers. In order effectively recycle ash, influence grain particle size thickness panel combination different layers various sizes have been studied, as well some environmental properties including leachability (EN-12457-4, NEN-7345) radioactivity tests. Based on obtained results, acoustic final composite material were similar or even better than those found porous concrete used for same application. According this study, produced presented no risk.
