摘　　要：研究矿渣掺量对阿利特-硫铝酸钡钙水泥性能的影响,当质量分数掺量为10%时,阿利特-硫铝酸钡钙水泥3 d、28 d的强度分别达到44.5 MPa和77.6 MPa。采用XRD、SEM等方法研究阿利特-硫铝酸钡钙水泥水化产物的组成、结构和形貌,并对该水泥的水化机理进行探讨。结果表明:当矿渣掺量质量分数为10%时,促进了该水泥的水化,有利于水泥强度的提高。Alite -barium calcium sulphoaluminate cement is a new kind of cementing material which has early - high strength and tiny expanstive performances. The influence of slag on cement performances was studied. Experimental results show that when the slag content is 10% the compressive strength of alite - barium calcium sulphoaluminate cement reachs 44.5 MPa and 77.6 MPa at 3 d and 28 d curing ages respectively. The constitution, structure and morphology of the hydration products were analyzed by means of SEM, XRD and DTA, and the cement hydration mechanism was discussed.
