摘　　要：主要利用大唐托县电厂生产粉煤灰提铝后剩余的工业废渣,替代工业废渣石英砂生产硅钙板。工业试验及性能测试结果表明,原料配方为:50%硅钙渣、20%水泥、17%脱硫石膏、13%粉煤灰,石棉纤维掺量为总重10%,另外加入少量纸纤维,生产的硅钙板性能符合JC/T 564.2—2008标准要求,产品的力学性能、抗冻性能、耐水性能等均取得了预期的效果,为以后大规模的工业化生产奠定了良好的基础。Calcium silicate board is produced by making use of the residue industrial waste after aluminum mentioning from fly ash in Datang Tuoxian Power Plant to replace the industrial waste quartz sand. Industrial test and performance test results showed that when the raw recipe is：50% calcium silicate slag, 20% cement, 17% FGD gypsum and 13% fly ash,asbestos fiber content of 10% of the total weight, adding a small amount of paper fiber, the performance of the obtained calcium silicate board is in line with the requirements of standard JC/T 564.2-2008 requirements. Mechanical properties,frost resistance and water resis- tance of the product achieved the expected effect,laying a good foundation for future large-scale industrial production.
