Radiation-proof concrete doped with rare earth composite material
The invention provides radiation-proof concrete doped with a rare earth composite material, and belongs to the field of radiation-proof concrete. The radiation-proof concrete is prepared from the following raw materials in parts by weight: 150 to 300 parts of cement, 600 to 900 parts of fine aggregate, 1150 to 1600 parts of coarse aggregate, 2 to 8 parts of water reducing agent, 2 to 5 parts of modified polypropylene fiber, 40 to 60 parts of radiation-proof material and 150 to 180 parts of water, wherein the radiation-proof material is a rare earth polymer composite material; and boron carbide micro powder is added into the modified polypropylene fiber. The radiation-proof concrete disclosed by the invention not only can play a better role in protecting X rays, gamma rays and neutrons at the same time, but also can reduce environmental pollution caused by heavy metals after concrete buildings are discarded; and the modified polypropylene fiber is added, so that the crack resistance of the concrete can be improved, and the neutron protection effect of the concrete can be further improved.
本发明提供了一种掺杂稀土复合材料的防辐射混凝土，属于防辐射混凝土领域。所述防辐射混凝土包括以下重量份的原料：水泥150～300份，细骨料600～900份，粗骨料1150～1600份，减水剂2～8份，改性聚丙烯纤维2～5份，防辐射材料40～60份，水150～180份；所述防辐射材料为稀土高分子复合材料；所述改性聚丙烯纤维中添加有碳化硼微粉。本发明的防辐射混凝土既能同时对X射线、γ射线和中子起到较好的防护作用，又能减少混凝土建筑废弃后导致的重金属对环境的污染；添加改性聚丙烯纤维既能提高混凝土的抗裂性能，又能进一步提高混凝土对中子的防护效果。
