| Abstract: | Study is made on making aerated concrete using low-silicon tailings of copper mine.Through series of experiments,the optimal proportioning of tailing aerated concrete is as follows:copper tailing 32%,silicon sand 34%,lime 20%,cement 8%,gypsum 6%,powdered aluminum 0.057%,the optimal water-solid ratio 0.53,and proper amount of foam stabilizer.The prepared tailing aerated concrete has average density of 619.1 kg/m3,and average compressive strength of 4.5 MPa,meeting the requirement of grade A3.5 and B06 qualif... |
