Anti-burst radiation shielding concrete and preparation method thereof
The invention relates to anti-burst radiation shielding concrete and a preparation method thereof. The concrete comprises the following components in percentage by mass (kg/m < 3 >): 100-150 parts of granulated blast-furnace slag powder, 600-700 parts of serpentine, 200-300 parts of cement, 800-1000 parts of yellow sand, 200-230 parts of water and 10-20 parts of high-efficiency water reducing agent. The volume fraction of steel fibers is 0.2%-0.5%, and the volume fraction of boron fibers is 0.1%-0.2%; and the mass ratio of the high-dispersity carbon nanotubes is 0.1%-0.5%. Through reasonable compatibility and equivalent substitution of the three types of fibers, crack development of the radiation shielding concrete at a high temperature can be effectively restrained, and the anti-burst performance of the concrete at the high temperature is effectively improved. The boron fibers and the high-dispersity carbon nanotubes play roles in improving the radiation shielding performance of the concrete and maintaining the structural integrity of the concrete, and the radiation shielding performance of the structure at high temperature is guaranteed.
本发明涉及一种抗爆裂辐射屏蔽混凝土及其配制方法，该混凝土的各组分按质量比为(kg/m3)：粒化高炉矿渣粉100～150，蛇纹石600～700，水泥200～300，黄砂800～1000，水200～230，高效减水剂10～20；钢纤维体积率0.2％～0.5％，硼纤维体积率0.1％～0.2％；高分散性碳纳米管质量比为1‰～5‰。三种类型纤维的合理配伍与等效取代可有效遏制辐射屏蔽混凝土在较高温度下的裂缝开展，有效提高混凝土高温下的抗爆裂性能。硼纤维与高分散性碳纳米管在提升混凝土辐射屏蔽性能，维持混凝土结构整体性方面均发挥效果，保障了结构在高温下的辐射屏蔽性能。
