摘　　要：本文通过不同水泥品种复配,辅以石膏及外加剂,研发了一种早强型水泥基材料。结果表明:当硫铝酸盐水泥掺入5%,无水石膏掺入5%时,复合水泥砂浆的抗折强度和抗压强度值较高;当硫铝酸盐水泥掺入8%、无水石膏掺入5%时的砂浆收缩值最小。In this paper, a kind of early strength cement based material was developed by combining different cement varieties with gypsum and admixture. Results showed that the strength of the composite cement mortar were high when sulphate aluminum and gypsum are both 5%. The shrinkage value of mortarwas minimized when the sulfur content was 8% and the gypsum content was 5%.
