在辐射屏蔽混凝土中氢元素含量对于中子屏蔽具有重要作用,水中含有较大比例的氢元素,因此材料中的结晶水含量在辐射屏蔽混凝土制造中是一个关键因素。以富含结晶水(质量分数m>6%)的橄榄岩为混凝土的粗、细集料,完成了混凝土配合比试验,配制了C30等级的防辐射混凝土。中子和γ射线屏蔽试验结果表明,同普通混凝土相比,橄榄岩混凝土中子辐射屏蔽性能明显增强,γ射线屏蔽性能也比较优异。

In radiation shielding concrete hydrogen content was important for neutron shielding,hydrogen ele-ments in water containing a large proportion,so the content of crystal water in the material was a key factor in radiation shielding concrete manufacturing.In this paper,one kind of peridotite with rich crystal water (mass fraction was higher than 6%)was used as coarse,fine aggregate of concrete.The mixture ratio of the concrete was experimentally designed and an anti-radiation concrete with C30 strength grade was produced.Neutron and gamma ray shielding test results show that,compared with ordinary concrete,neutron radiation shielding prop-erties of peridotite concrete significantly enhanced,gamma ray shielding performance was excellent.
