摘　　要：探讨了高炉矿渣及石膏和石灰石参与下阿利特—硫铝酸盐水泥的性能。结果表明，在阿利特—硫铝酸盐水泥熟料中掺加较多量矿渣，强度的降低幅度较小，当有适量的石膏及石灰石存在时，水泥的7d、28d强度可赶上或超过不掺矿渣的试样。这一结果归结为所造成的AFt生长的良好条件及对矿渣的良好激发作用以及对硅酸盐矿物水化的促进作用；掺加矿渣，水泥的凝结时间有所延长。Properties of alite -sulphoaluminate cement clinker with addition of blast -furnace slag, gypsum and limestone are discussed. The results show that the strength of cement with higher slag content is only reduced to a small extent. The 7d and 28dstrengths of such cement will match or even higher than the cement without slag when the amount of gypsum and limestone added are appropriate. This result is attributed to the better condition of formation of AFt, to the better activating action of slag, and, in turn,to the promotion of hydration of silicates. Howerer, the setting time of the cement with slag is somewhat longer.
