摘　　要：把铝型材厂工业废渣预处理成铝废渣熟料，分析处理前后铝废渣的综合性能。在原轻质砖配方的基础上掺入一定量的铝废渣熟料，调整配方及烧成曲线，制备出性能良好的轻质砖，对所制备轻质砖进行强度、吸水率、比重、SEM、XRD等测试分析，结果显示其抗折强度在19MPa以上，约为行业标准值的2倍，较原轻质砖配方有显著提升，吸水率为0．296％，比重在1．33～1．40g／cm^3，通过XRD分析，其主晶相为AlPO4和SiO2，及少量的α—Al2O3晶相。SEM图上可观察到添加铝废渣后的试样的大小孔相间均匀，且多为圆孔，贯穿孔比未添加铝废渣的试样少，骨架连接完整。Analysis the comprehensive performance of aluminum profile residue both before and after preprocessing. Doping a certain amount of aluminum profile residue to original light brick formula, adjusting the sintering curve to sinter . The test of strength, water absorption, proportion, SEM, XRD display a well comprehensive performance. The strength reach 19 MPa, two times the national Standard, it＇s a significantly improve compare to the original light brick recipe, and the water absorption is 0.29%, proportion range from 1.33 to 1.40 g/cm^3. Its Main crystalline phases are AlPO4 and SiO2, as well as little α-Al2O3 , by XRD analysis. The SEM pictures show a complete Skeleton, the pores are uniform and round are mostly, the through hole is significantly less than the original light brick recipe.
