Influence of secondary aluminum dross (SAD) on compressive strength and water absorption capacity properties of sandcrete block

Secondary aluminum dross (SAD) is a hazardous by-product of the aluminum smelting industry. Among various recycling options of this waste, construction and building materials applications is one of the value-added options to end dumping. The present study, thereby, investigates the influence of SAD...
