More Information
Summary:The invention relates to an industrial waste slag-based energy saving and environmentally-friendly brick which is characterized by comprising 15-25 percent by weight of cobalt waste slag, 50-60 percent by weight of red mud, 15-20 percent by weight of active substances and 4-10 percent by weight of additive; the cobalt waste slag is industrial waste slag after acid leaching of a cobalt ore and comprises 40-60 percent by weight of SiO2, 10-25 percent by weight of Al2O3, 3-8 percent by weight of Fe and 2-8 percent by weight of CaO; the red mud comprises 20-30 percent by weight of SiO2, 35-50 percent by weight of CaO, 5-15 percent by weight of Al2O3, 8-18 percent by weight of Fe and 2-6 percent by weight of Na2O. The industrial waste slag-based energy saving and environmentally-friendly brickprovided by the invention has the benefits that a formula is simple, the content of the slag in the formula is high, the content of the cobalt waste slag and the red mud reaches 75 percent or above 75percent, and the environm
