Barite-based radiation-proof concrete
The invention discloses barite-based radiation-proof concrete, and belongs to the technical field of building materials. The radiation-proof concrete comprises the following components in parts by weight: 270-300 parts of cement, 1350-1500 parts of barite, 700-850 parts of barite sand, 350-500 parts of boron ore sand, 60-90 parts of an expanding agent, 7-10 parts of a water reducing agent, 70-85 parts of an admixture and 150-200 parts of water, wherein the apparent density of the barite is 3800-3950 kg/m<3>, and the grade of the barite is 8-20 mm; the grade of the barite sand ranges from 0.13 mm to 1.25 mm; the grade of the boron ore sand is 0.17 to 2.74 mm; and the expanding agent is a UEA expanding agent. The radiation-proof concrete disclosed by the invention has good mechanical properties and thermal stability, also has good anti-radiation performance, and can effectively prevent gamma ray radiation and neutron radiation.
本发明公开了一种基于重晶石的防辐射混凝土，属于建筑材料技术领域。所述防辐射混凝土包括以下重量份组分：270‑300份水泥、1350～1500份重晶石、700～850份重晶石砂、350～500份硼矿砂、60‑90份膨胀剂、7‑10份减水剂、70‑85份掺合料和150‑200份水，其中，所述重晶石表观密度为3800～3950kg/m3，级配为8～20mm；所述重晶石砂的级配为0.13～1.25mm；所述硼矿砂的级配为0.17～2.74mm；所述膨胀剂为UEA膨胀剂。本发明的防辐射混凝土具有良好的力学性能和热稳定性能，并且具有良好的防辐射性能，能够有效防γ线辐射和中子辐射。
