Concrete for moderating and absorbing neutrons and preparation method thereof
The invention belongs to the technical field of concrete building materials, and discloses concrete for moderating and absorbing neutrons and a preparation method thereof.The concrete is prepared from, by weight, 400-550 kg/m < 3 > of boron-containing cement, 140-300 kg/m < 3 > of functional admixture, 2450-2850 kg/m < 3 > of heavy coarse and fine aggregate, 6-15 kg/m < 3 > of metal hydride, 8-12 kg/m < 3 > of water reducing agent, 3-5 kg/m < 3 > of rheological agent and 2-6 kg/m < 3 > of stabilizer, and the water-cement ratio is 0.35-0.45. According to the invention, the metal hydride is introduced into the concrete for the first time, and is matched with other raw materials, so that the mechanical property and durability of the concrete can be ensured, the dual radiation protection functions of moderating neutrons and absorbing neutrons can be realized, and the concrete is an environment-friendly functional concrete material.
本发明属于混凝土建筑材料技术领域，公开了一种慢化和吸收中子的混凝土及其制备方法，按每方重量计，包括以下原料：含硼水泥400～550kg/m3、功能掺合料140～300kg/m3、重质粗细骨料2450～2850kg/m3、金属氢化物6～15kg/m3、减水剂8～12kg/m3、流变剂3～5kg/m3、稳定剂2～6kg/m3，水灰比0.35～0.45。本发明首次将金属氢化物引入到混凝土中，再配合其它原料，可以在保证混凝土力学性能和耐久性能的同时，实现慢化中子和吸收中子的双重防辐射功能，是环境友好型功能混凝土材料。
