摘　　要：研究了废黏土砖粉(WFCB)作为再生胶凝材料,对水泥标准稠度用水量、凝结时间和抗压强度的影响。结果表明,废黏土砖粉加入到水泥中,会引起水泥标准稠度用水量的增加和凝结时间的缩短;废黏土砖粉的火山灰活性较低,用作再生胶凝材料会降低水泥的抗压强度。Effect of waste fired clay brick powder （ WFCB ） used as regenerated binding material on water requirement of normal consistency,setting time and compressive strength of cement are studied in this paper. The results show that,WFCB can increase the water requirement of normal consistency of cement and shorten the setting time. WFCB has low pozzolanic activity and it can decrease the compressive strength of cement if used as regenerated binding material.
