石灰石对阿利特—硫铝酸盐水泥性能的影响

Influence of Lime Stone on Alite - Sulpho - Aluminate Cement Properties

研究了石灰石对阿利特—硫铝酸盐水泥强度、凝结时间、干缩性等性能的影响.发现石灰石在较大掺量范围内可以促进水泥强度的发展;石灰石可延长水泥的终凝时间,而使初凝有所缩短;掺加石灰石使水泥的抗干缩能力提高.

The effects of limestone on alite - sulpho - aluminate cement strength, setting time and dry shrinkage are studied. Results show that limestone can improve the strength development in a large adding range. It can defer the final setting time and shorten the initial setting time. The cement mortar made a little dry shrinkage.
