摘要
预应力压浆料的流动度保持及耐久性对预应力混凝土的施工及构件质量有着重要的影响,该文对国内外有关后张预应力压浆技术研究进展、预应力压浆料流动性保持、高温下预应力压浆料流动性保持、预应力压浆料耐久性性能进行概述总结。
The fluidity retention and durability of pre-stressing grouting material have an important impact on the construction and component quality of pre-stressing concrete.This paper summarized the research progress of post-tensioned pre-stressing grouting technology at home and abroad,the fluidity retention and durability of pre-stressing grouting material,and the fluidity retention of pre-stressing grouting material at high temperature.
