摘　　要：研究了超细矿渣(SFS)对硫铝酸盐水泥(SAC)砂浆力学性能和干缩性能的影响,并与普通硅酸盐水泥(PC)砂浆进行了对比试验。结果表明,(1)SAC和PC砂浆强度都随SFS掺量的增加呈先增后减趋势,对于SAC砂浆,SFS掺量为20%时其各龄期抗折抗压强度为最佳;对于PC砂浆,该值为30%;(2)在试验条件下,SFS掺量为20%的SAC砂浆和SFS掺量为30%的PC砂浆的改性效果最好;(3)掺入SFS后,SAC和PC砂浆结构更致密,总孔隙率降低。The impact of superfine slage（SFS） on drying shrinkage and mechanical property of sulphoanuminate cement mortar（SAC） was studied, compared with that of ordinary portland cement（PC）. The results shows as followings,（1） with the adding of SFS,the strength of SAC and PC mortar increases first and decreases later, and for SAC mortar,the bending and compressing strength in curing time reaches the best when the content rate of SFS is 20%, and for PC mortar, the value is 30%;（2） in this experiment,modification effect is best when adding rate of SFS is 20% in SAC mortar and 30% in PC mortar; （3） by adding SFS, the structure of SAC and PC mortar gets more compact and the total porosity decreases.
