聚羧酸系高效减水剂在泵送混凝土中的应用

聚羧酸系高效减水剂作为一种新型的减水剂，目前主要用于铁路客运专线工程、特殊混凝土和高性能混凝土中，在配制高性能泵送混凝土得到了很好的效果，但也常容易出现一些问题。本文就聚羧酸系高效减水剂在配制泵送混凝土中常出现问题的加以分析，并给出一些解决办法。

Polycarboxylate of superplasticizer in the preparation of high-performance pumping concrete issues of common

With the rapid development of the construction industry, not only to the growing demand for concrete and concrete on the performance requirements are atso getting higher and higher. Polycarboxylate of superplasdcizer as a new water reducer, mainly for railway passenger line project, special and concrete high-performance concrete, in the preparation of high-performance concrete pumping has been very good results, but also often prone to this or that the problem, to the construction progress and quality of construcdon cause trouble. This paper is polycarboxylate of super- plasticizer m the preparation of concrete pumping often the causes of problems to be analyzed, and presented some solutions.
