装配式混凝土结构灌浆材料的性能试验与施工技术

Performance test and the construction technology of cementitious grouting material used in precast reinforced concrete structure

浆锚连接是装配式混凝土结构的节点设计与构造中的湿法连接工艺,浆锚连接的质量与灌浆材料的性能、质量和施工水平有关。以浆锚连接和间接连接为对象,研究了水泥基灌浆材料的试验内容、方法和性能要求等。结合套筒灌浆连接,研究了水泥基灌浆材料的施工与质量控制要求,对于装配式混凝土结构节点设计与施工提供了参考。

Grouting anchor connections are nodes connected by wet process in the design and construction of prefcast reinforced concrete structure, grouting anchor connection quality are depended on grouting material performance, quality and construction level.Taking grouting anchor connections and indirect connection as the object, cementitious grouting materials, test content, method and performance requirements, etc.were studied.Combined with pipe casing connection,the cement-based grouting materials of construction and quality control requirements were researched, which provided reference for design and construction ofprecast reinforced concrete structure.
