摘　　要：针对是否可以用M 32.5砌筑水泥代替原P·C 32.5、P·C 32.5R复合硅酸盐水泥这一问题,比较分析了GB 175-2007《通用硅酸盐水泥》和GB/T 3183-2017《砌筑水泥》。相对于原P·C 32.5、P·C 32.5R复合硅酸盐水泥,M 32.5砌筑水泥的适用范围非常有限,组成略微复杂,终凝时间更长,存在体积安定性风险,不能用于可能发生碱骨料反应和Cl-含量要求较低的工程。In response to the question of whether M 32.5 masonry cement can replace the original P.C 32.5 and P.C 32.5R composite Portland cements,a comparative analysis was conducted based on GB 175-2007 General Portland Cement and GB/T 3183-2017 Masonry Cement.In comparison to the original P-C32.5 and P.C 32.5R composite Portland cements,M 32.5 masonry cement has a very limited scope of application,slightly more complex composition,longer setting time,and carries a risk of volume instability.It cannot be used in projects that possibly experience alkali-ag-gregate reactions or require lower Cl- content.
