聚羧酸高效减水剂以其高减水率、低坍落度损失、低碱含量,与水泥相容性好等优良的性能成为近年来世界各国研究的热点,但其产品价格较高。将聚羧酸高效减水剂与萘系、氨基磺酸盐、脂肪族高效减水剂复合使用在保证和易性的同时达到降低成本的目的。本文研究了聚羧酸系高效减水剂与其它高效减水剂复合使用对混凝土力学性能的影响,其结果对实际工程具有一定的指导意义。
In recent years, polycarboxylate superplasticizer has become the focus of research in various countries in the world due to its excellent properties such as high water reduction, low slump loss, low alkali content and good compatibility with cement. However, the price of its products is high. The polycarboxylate superplasticizer and naphthalene, sulfamate, aliphatic superplasticizer used in combination to ensure ease of work while achieving the purpose of reducing costs. In this paper, the effect of polycarboxylate superplasticizer combined with other superplasticizer on the mechanical properties of concrete is studied. The results have certain guiding significance for practical engineering.
