大体积防辐射混凝土研究综述

料研REVIEW ON THE LARGE VOLUME RADIATION-PROOF CONCRETE

核辐射危害人类正常生活,但是医疗中有不可避免。文中介绍了大体积混凝土温控技术研究现状,并重点从防辐射混凝土原材料、混凝土配合比等方面介绍了防辐射混凝土的研究现状,分析了大体积防辐射混凝土研究方面的不足,发现大体积防辐射混凝土研究主要集中于混凝土的制备及原材料对屏蔽性能分析上,而对其耐久性研究较少,与大体积混凝土的水化热分析结合研究较少,对防辐射混凝土在超厚、超大体积情形下温控措施研究进行思考及展望。

Although nuclear radiation endangers the normal life of human beings,it is unavoidable in medical treatment.This paper reviews the research status of temperature control technology of mass concrete,and introduces the research status of radiation-proof concrete from the aspects of raw materials and concrete mix proportion.It is found that the research of large-volume radiation-proof concrete mainly focuses on the preparation of concrete and the analysis of shielding performance of raw materials,but less on its durability.Combined with the hydration heat analysis of mass concrete,the temperature control measures of radiation-proof concrete in the case of super-thick and super-mass are considered and prospected.
