Properties of concrete mortar incorporating recycle pulverized sandblasting waste as additives.

ABSTRACT: Sandblasting waste is a by-product obtained from the ship maintenance industry which is rich in silica content. This waste has a smaller particle size compared with typical sand and contains a high prevalence of impurities, so it is categorized as toxic and hazardous materials based on Indonesian Law. Furthermore, it also has not been efficiently harnessed, with most of it being relegated to disposal in waste landfills. To solve those problems, this research aimed to reduce the waste by reuse and recycle the sandblasting waste. In this study, the Pulverized Sandblasting Waste (PSW) used as additives in concrete mortars. Prior to use as an additive in mortar, the sandblasting waste was pretreated using chemical and mechanical processes. The mechanical pre-treatment was performed by pulveriz
