摘　　要：辽宁省的工业废渣粉煤灰、硅锰渣和硼泥排量巨大,用这些废渣替代部分水泥、石子和河沙配制混凝土既环保利废、具有显著的经济效益和社会效益,又有利于可持续发展.采用辽阳市混凝土常用原材料以及灯塔昌明墙体材料厂生产的硼泥陶粒,通过正交试验优化配合比,分析了水泥用量、粉煤灰掺量、硅锰渣的掺量对硼泥陶粒混凝土抗压强度的影响规律.实验结论,当水泥用量为480 kg/m3、粉煤灰掺量占胶凝材料质量的10%、硅锰渣的掺量为细骨料体积的60%时可以配制出LC30轻骨料混凝土.Liaoning Province has quite a few industrial residues like fly ash, silicon manganese slag and boron mud, which can be used to replace some concrete, stones and river - sand as construction materials with much economic and social benefit to sustainable development. This research uses the popular raw materials for producing concrete in Liaoyang City and the boron mud ceramsite produced by Dengta Thriving Wall Materials Plant and gives an orthogonal test to optimize the mixture ratio, analyze the compressive strength of the cement dosage, the dosage of fly ash, and the silicon manganese slag dosage of boron sludge ceramsite concrete. The test has the following conclusions： the production of LC30 lightweight aggregate concrete needs the following requirements： the dosage of cement is 480 kg/m^3 , the fly ash accounts for 10% of the gelled material dosage, and the content of silicon manga- nese slag accounts for 60%.
