摘要
利用工业固体废弃物铜渣制备无机胶凝材料,并对其胶砂试件的高温力学性能进行了实验研究.分别制备了普通硅酸盐水泥-铜渣复合胶凝体系（C SC -x）和碱激发铜渣胶凝体系（CSA -x）,测试了常温及100℃、200℃、400℃、600℃ 、800℃、1000℃、1200℃ 高温作用后的质量损失、残余抗折强度和残余抗压强度.结果表明：200℃后,CSA-x体系的质量损失率低于CSC-x体系; CSA-x体系表现出较好的耐高温性能, 1200 ℃高温作用后CSA-x体系的残余抗压强度为常温时的3-4 倍.
Focused on the preparation of inorganic cementitious materials by using industrial solid waste copper slag,and its mechanical properties after exposure to high temperatures. Copper slag cementitious system with different slag replacements(CSC-x) and alkali copper slag cementitious system(CSA-x) with different alkali concentrations(CSA-x) were prepared. Mass loss,flexural and compressive strengths of the mortar specimens at room temperature and after the exposures to 100 ℃,200 ℃,400 ℃,600 ℃,800 ℃,1000 ℃,1200 ℃ were tested. The results showed that: Above 200 ℃,the mass loss of CSAx system was lower than CSC-x system. The residual compressive strength of CSA-x system after the exposure to 1200 ℃ was 3-4 times higher than that at room temperature.
