2020-6-14Abstract Geopolymer concrete GPC is becoming a sustainable concrete when comparing to ordinary Portland cement OPC concrete. This investigation is mainly focused on the preliminary study on fly ash FA and ground granulated blast furnace slag GGBS based GPC using copper slag CS and vermiculite VM as fine aggregate replacement at different levels 0, 20 and 40.
2020-7-15Copper slag also has a high strength-to-weight ratio, making it an effective option in concrete, or as a fill material under the roadway. When added to concrete, it makes the paved surface less porous, which minimizes problems with moisture and freezing. It also makes concrete more fire resistant, and helps to slow the spread of heat and flames.

Copper slag is the one of the industrial waste available. It is a by product of copper production from copper core. During smelting, a molten pool of copper forms at the bottom of the furnace while a layer of impure metal, which is the slag, is drained off from the top. Copper slag and lime form cementateous material on hydration.
