摘　　要：陶瓷抛光砖的产量已位居我国瓷砖产量第一位，其生产的陶瓷抛磨废料已严重污染环境。笔者使用陶瓷抛磨废料替代部分石粉和砂制备免烧砌墙砖，研究结果发现：在未添加激发剂时，陶瓷废料的加入降低了砖坯强度；当加入1％自制激发剂后，与陶瓷废料活性成分生成硅酸钙（CSH）和钙矾石（AFt），可使砖坯强度提高2～3倍，并可明显降低生产成本，最大降幅可达26．8％。With the development of the manufacturing sector of polished brick,the polished waste material had seriously pol-luted the environment.This paper has studied with polished waste material to replace stone powder and sand to manufac-ture baking-free brick.Results showed that without adding booster,the strength of baking-free brick gradually de-creased with the increase of the polished waste material content.Adding 1% booster improved the strength of baking-free brick 2 to 3 times,significantly reduced produce cost of brick raw material,the biggest reduce rate reached 26.8%.
