摘要: 针对科研和工程需要，对密度4.60 t/m3屏蔽γ射线防辐射混凝土配合比设计、施工工艺、混凝土密实度和屏蔽均匀性等进行了系统研究，解决了高密度混凝土施工中的均匀性、密实度问题，提出了射线检测屏蔽混凝土密度和屏蔽均匀性的方法，总结了高密度混凝土施工的技术措施。经工程实践证明，配合比设计和施工工艺可行，保证了工程实体施工质量。Abstract: According to the demand for research and construction project, a series of systematic experiments and studies on shielding γ-ray radiation concrete with the density of 4.60 t/m3 were made in such aspects as mix ratio design, construction technology, uniformly shielding etc. Such issues as uniformity in the construction and compactness were solved. The ray test method for uniformly shielding concrete was presented and some technical steps for this high-density concrete used in the process of test design or construction were summed up. A series of tests and practical applications show that this technology of mix ratio design and construction is feasible.
