摘　　要：本文使用陶瓷抛光渣取代天然石英粉制备纤维增强硅酸钙板,探讨了陶瓷抛光渣的掺量对纤维增强硅酸钙板抗折强度的影响,并通过XRD和SEM分析了陶瓷抛光渣的掺入对纤维增强硅酸钙板内部的矿物晶体种类、结晶程度和晶体形貌的影响。实验结果表明,掺加陶瓷抛光渣不会改变纤维增强硅酸钙板内部主要矿物晶体的种类,但是矿物晶体的发育程度会随着掺量的增加而降低,并最终使纤维增强硅酸钙板的抗折强度下降。少量的陶瓷抛光渣取代石英粉生产纤维增强硅酸钙板是可行的,考虑到生产和工程实际,陶瓷抛光渣取代石英粉的取代量应控制在15%以内。This paper aims at replacing natural quartz powder by ceramic polished slag to prepare fiber reinforced calcium silicate board. The influence of ceramic polished slag content on flexural strength of the reinforced calcium silicate board was studied. And the influences of ceramic polished slag content on the type of mineral crystal, crystallization degree and crystal morphology were analyzed through XRD and SEM test. The results were shown that the mineral crystal type of the reinforced calcium silicate board will not change with the content of ceramic polished slag. But the crystallization degree of the mineral crystal will be reduced with the increase of slag content, and finally make the flexural strength decreased. As a result, the replacement of quartz power to a small amount of ceramic polished slag is quite feasible. Considering the production and the engineering reality, the adding quantity of the alternative ceramic polished slag should be controlled within 15%.
