摘　　要：实验对废弃红砖和炉渣的化学成分进行了分析，用激光粒度仪研究了粉磨后原料粉体的粒度分布，通过单掺和双掺的方式研究了红砖粉和炉渣粉对水泥强度、需水量、凝结时间和安定性的影响，并对作用机理进行了讨论。研究表明，红砖粉和炉渣作为活性混合材掺量为5O％（炉渣为1O％）时仍能制备出性能较好的P·C32．5级生态水泥。为废弃建筑红砖的处理提供新的途径。The chemical composition of abandoned red-brick and boiling furnace cinder （BFC） is analyzed. The size distribution of raw powder was studied by laser particle size analyzer. The strength of cement, water demand, setting time and stability were studied when the abandoned red-brick and the BFC was mixed into the cement alone or together. In addition to this, the mechanism was discussed. The results show that, the P· C 32.5 ecological cement can be prepared when 40% of the abandoned red-brick and 10% of the BFC are mixed into the cement together.
