本文通过掺加聚羧酸减水剂的水泥净浆和混凝土流动性的试验,对Marsh筒法能否用于评价聚羧酸系减水剂与水泥相容性进行了研究。结果表明,用Marsh筒法评价聚羧酸系减水剂与水泥的相容性是可行的,其试验结果与混凝土试验有一定的相关性,能够指导混凝土的生产。
In this paper, by the test of cement paste mixed with polycarboxylate superplasticizer and concrete fluidity, whether Marsh cylinder method can be used to evaluate the compatibility of polycarboxylate superplasticizer with cement was studied. The results show that it is feasible to evaluate the compatibility of polycarboxylate superplasticizer with cement by Marsh cylinder method. The test results have some correlation with concrete test and can guide the production of concrete.
