Anti-radiation ultra-high performance concrete and preparation method thereof
The invention provides anti-radiation ultra-high performance concrete and a preparation method thereof, and belongs to the field of anti-radiation building materials. The concrete comprises the following raw materials: 650-800 kg/m < 3 > of cement, 100-150 kg/m < 3 > of fly ash microspheres, 130-200 kg/m < 3 > of silica fume, 40-60 kg/m < 3 > of barite powder, 1100-1700 kg/m < 3 > of ore sand, 100-200 kg/m < 3 > of fibers, 20-30 kg/m < 3 > of a shrinkage and viscosity reduction type water reducing agent, 50-80 kg/m < 3 > of an expanding agent and 170-200 kg/m < 3 > of water. The apparent density of the concrete is 2650-3200kg/m < 3 >, the compressive strength grade can reach C100 or above, and the concrete has good working and mechanical properties and volume stability, can effectively improve the toughness, impact resistance, durability and gamma-ray radiation resistance of concrete members, and has important practical application value.
本发明提供一种防辐射超高性能混凝土及其制备方法，属于防辐射建筑材料领域。所述混凝土包括以下原料：水泥650～800kg/m3，粉煤灰微珠100～150kg/m3，硅灰130～200kg/m3，重晶石粉40‑60kg/m3，矿砂1100～1700kg/m3，纤维100～200kg/m3，减缩降粘型减水剂20～30kg/m3，膨胀剂50～80kg/m3和水170～200kg/m3；所述混凝土的表观密度为2650～3200kg/m3，抗压强度等级可达C100以上，具有良好的工作、力学性能以及体积稳定性，可有效提升混凝土构件的韧性、抗冲击性能、耐久性能及防γ射线辐射性能，具有重要的实际应用价值。
