用山西朔州当地价格较为低廉的火力发电厂燃煤炉底渣（即煤渣）并配合一定数量的石灰石，进行了复合水泥的试验研究。重点研究了煤渣、石灰石复合使用时，对水泥标准稠度用水量及其力学性能的影响；并采用XRD、SEM，研究了复合水泥的水化机理。研究结果表明：煤渣与石灰石复掺使用时，可以降低水泥标准稠度用水量，强度也能达到要求指标；当石灰石掺量为10%、煤渣掺量为30%时，可以制得28 d抗压强度高达60 MPa的复合水泥。%The composite cement was prepared with Shanxi Shuozhou local low-price power plant cinder in the experimental study. Im-pacts of cinder and limestone on standard cosistency water consumption and mechanical properties of the composite cement were re-searched, and the hydration mechanism was studied. The results show that cinder and limestone together can reduce standard cosisten-cy water cosumption of the composite cement, and the strength can also reach standard indexes;and when limestone ratio is 10%and cinder ratio is 30%, composite cement with 60 MPa 28 d compressive strength can be prepared.
