Composite anti-radiation concrete and preparation process thereof
The invention belongs to the technical field of engineering materials, and particularly relates to composite radiation-proof concrete and a preparation process thereof. According to the technical key point, the concrete is prepared from the following components in parts by weight: 230 to 380 parts of Portland cement, 45 to 90 parts of slag powder, 30 to 180 parts of fly ash, 60 to 120 parts of steel slag powder, 1100 to 1400 parts of fine aggregate, 1000 to 1500 parts of composite smelting slag coarse aggregate, 150 to 180 parts of water and 10 to 20 parts of additive. The composite anti-radiation concrete provided by the invention takes the composite smelting slag as coarse aggregate, the smelting slag is taken as a main raw material of an inner core of the composite anti-radiation concrete, and carbon powder and sodium alginate gel are supplemented; wherein the Fe element, the Mn element and the Cr element in the smelting slag can play a role in shielding gamma, slow neutron and proton radiation.
本发明属于工程材料技术领域，具体涉及一种复合防辐射混凝土及其制备工艺。其技术要点如下，各组分按重量份数计包括：硅酸盐水泥230～380份，矿渣粉45～90份，粉煤灰30～180份，钢渣粉60～120份，细骨料1100～1400份，复合冶炼渣粗骨料1000～1500份，水150～180份和外加剂10～20份。本发明提供的复合防辐射混凝土以复合冶炼渣为粗骨料，其内核以冶炼渣为主要原料，并辅以碳粉和海藻酸钠凝胶；其中冶炼渣中的Fe元素、Mn元素、Cr元素可以发挥屏蔽γ和慢中子、质子辐射的作用。
