High-temperature-resistant radiation-proof concrete and preparation method thereof
The invention relates to high-temperature-resistant radiation-proof concrete and a preparation method thereof. The concrete comprises the following components in percentage by mass (kg/m < 3 >): 600-700 parts of serpentine, 1000-1100 parts of serpentine sand, 500-600 parts of a cementing material, 200-230 parts of water and 8-9 parts of a water reducing agent. The high-temperature-resistant radiation-proof concrete is optimally designed, the neutron transmission resistance and the long-term mechanical property of the shielding concrete after high-temperature damage are considered at the same time, and the concrete is optimally designed at the beginning of mix proportion design, so that the comprehensive performance of the reactor pit wall and the near-reactor-core concrete under emergency conditions such as reactor core melting is effectively improved; by matching with bottom plate sacrifice concrete, the radiation shielding performance of the material after thermal damage can be effectively improved, the nuclear radiation threat is reduced, and the ecological environment safety and the personnel health are guaranteed.
本发明涉及一种耐高温防辐射混凝土及其配制方法，该混凝土的各组分按质量比为(kg/m3)：蛇纹石600～700，蛇纹砂1000～1100，胶凝材料500～600，水200～230，减水剂8～9。对耐高温防辐射混凝土进行优化设计，同时考虑了高温损伤后屏蔽混凝土的防中子透射性能与长期力学性能，在配合比设计之初即对混凝土进行优化设计，有效提高了堆坑壁、近堆芯混凝土在堆芯熔融等应急情况下的综合性能，与底板牺牲混凝土配合，可有效提高热损伤后材料辐射屏蔽性能，减少核辐射威胁，保障了生态环境安全与人员健康。
