核电厂重混凝土的施工质量控制

摘要

The paper introduces the function and characteristics of biological protective heavy-concrete,and its main application scope and role in Fangjiashan nuclear power project.From the aspects of raw material selection,mixing ratio test,heavy concrete production,the paper discusses the main control points of heavy concrete construction process,points out the basic characteristics of heavy concrete construction,and put forward measures to prevent density non-uniformity during heavy concrete construction and to control slump during transportation.Results prove that reasonable construction process control can assure the engineering quality.%介绍了生物防护用重混凝土的功能和特点,以及在方家山核电工程的主要应用范围和作用,从原材料选购、配合比试验、重混凝土生产、现场浇注等方面入手,论述了重混凝土施工过程的主要控制重点,指出了重混凝土施工的基本特点,提出了防止重混凝土施工密度不均匀及运输过程坍落度控制的措施。结果证明,合理的施工过程控制,能使工程质量得到保证。
