Anti-gamma-ray ultra-high performance concrete and preparation method thereof
The invention provides anti-gamma-ray ultra-high performance concrete and a preparation method thereof. The anti-gamma-ray ultra-high performance concrete comprises the following components in percentage by mass: 30-50% of P.O52.5R ordinary Portland cement; 5-20% of barium sulfate cement; 7-10% of silica fume; 20-27% of quartz sand; 6-7% of steel fiber; 1.5-2% of a water reducing agent; and the balance of water. The concrete disclosed by the invention has the characteristics of ultrahigh strength, ultrahigh service life, high fracture toughness, gamma-ray radiation prevention and the like; the nuclear radiation protection capability and the safety reserve of a nuclear engineering structure are greatly improved, the service life of the nuclear engineering structure is greatly prolonged, the structure thickness and the construction difficulty are reduced, auxiliary measures are reduced, and compared with a traditional composite structure composed of common reinforced concrete and a radiation-proof material, the construction cost can be greatly reduced; and the problem that a building main body structure and a nuclear radiation protection structure of a traditional material engineering system cannot be unified and can only be compounded is solved, and the material can be used for building the main body structure and can also be used as a foundation engineering material of the nuclear radiation protection structure.
本发明提供一种防γ射线的超高性能混凝土及其制备方法，包括以下质量百分比的组分：P.O52.5R普通硅酸盐水泥30‑50％；硫酸钡水泥5‑20％；硅灰7‑10％；石英砂20‑27％；钢纤维6‑7％；减水剂1.5‑2％；其余为水。本发明的混凝土具有超高强度、超高使用寿命、高断裂韧性、防γ射线辐射等特点；大幅提高核工程结构的核辐射防护能力、安全储备与使用寿命，降低结构厚度与施工难度，减少附属措施，相比传统普通钢筋混凝土与防辐射材料组成的复合结构，建设成本可以大幅降低；解决传统材料工程体系建筑主体结构与核辐射防护结构不能统一，只能复合的问题，既能用于构筑主体结构、又能用作核辐射防护结构的基础工程材料。
