Water-absorbent resin neutron-radiation-proof shielding high-performance concrete and preparation method thereof
The invention discloses a water-absorbent resin neutron-radiation-proof shielding high-performance concrete and a preparation method thereof, and belongs to the technical field of building materials. The neutron radiation shielding prevention high-performance concrete is prepared from the following raw materials in parts by weight: 800 to 860 parts of cement, 120 to 170 parts of silica fume, 130 to 170 parts of fly ash, 230 to 300 parts of coarse aggregate, 780 to 820 parts of fine aggregate, 100 to 150 parts of water and 20 to 50 parts of a water reducing agent, and further comprises 0.1 to 0.3 weight percent of water-absorbent resin. By doping the water-absorbent resin into the concrete, on one hand, the hydrogen element content can be greatly increased, and then the neutron radiation resistance of the concrete is remarkably improved; on the other hand, in 7-day and 28-day ages, the humidity reduction in the concrete can be obviously delayed, the self-constriction of the concrete is inhibited, and an internal curing effect is achieved. A certain amount of water-absorbent resin is added into the concrete material, so that the shielding effect of the concrete test block on fast neutrons is remarkably improved.
本发明公开了一种吸水树脂防中子辐射屏蔽高性能混凝土及其制备方法，属于建筑材料技术领域。原料按重量份计包括：水泥800～860份、硅灰120～170份、粉煤灰130～170份、粗骨料230～300份、细骨料780～820份、水100～150份和减水剂20～50份，所述吸水树脂防中子辐射屏蔽高性能混凝土中还包括0.1～0.3wt％的吸水树脂。在混凝土中掺加吸水树脂，一方面可大幅度提升氢元素含量，进而显著提升混凝土抗中子辐射性能；另一方面在7天和28天龄期能明显延缓混凝土内湿度下降，抑制其自收缩，具有内养护作用。本发明通过在混凝土材料中加入一定量的吸水树脂，显著提高了混凝提试块对快中子的屏蔽效果。
