Radiation-proof concrete admixture, concrete, condensate and preparation method thereof
The invention provides an anti-radiation concrete admixture, concrete, a condensate and a preparation method of the anti-radiation concrete admixture. Belongs to the technical field of radiation-proof concrete. The anti-radiation concrete admixture comprises the following components in parts by weight: 1409 parts of magnetite coarse aggregate, 641 parts of serpentine fine aggregate, 403 parts of cement and 173 parts of granulated blast furnace slag. The radiation-proof concrete composition is prepared from the following components in parts by weight: 1409 parts of magnetite coarse aggregate, 641 parts of serpentine fine aggregate, 403 parts of cement, 173 parts of granulated blast furnace slag, 1.7 parts of a water reducing agent, 8.6 parts of a defoaming agent and 230 parts of water. The radiation-proof concrete condensate is obtained by curing the radiation-proof concrete composition. According to the radiation-proof concrete, the characteristics that the magnetite is large in density and the radiation-proof capability at high temperature is more stable than those of barite, hematite and other materials and the serpentine structure contains crystal water and is more stable at high temperature are utilized, the gamma ray and neutron ray shielding capability is integrated, and the radiation-proof concrete has good compressive strength and high-temperature mechanical properties.
本申请提供一种防辐射混凝土掺和料、混凝土、固化物及其制备方法。属于防辐射混凝土技术领域。防辐射混凝土掺和料按重量份计包括如下组分：磁铁矿粗骨料1409份、蛇纹石细骨料641份、水泥403份、粒化高炉渣173份。防辐射混凝土组合物，按重量份计包括如下组分：磁铁矿粗骨料1409份、蛇纹石细骨料641份、水泥403份、粒化高炉渣173份、减水剂1.7份、消泡剂8.6份和水230份。防辐射混凝土固化物由防辐射混凝土组合物固化而获得。上述防辐射混凝土利用磁铁矿密度大，高温下防辐射能力相比重晶石、赤铁矿等材料稳定的特点以及蛇纹石结构中含有结晶水，高温下比较稳定的特点，综合了伽马射线和中子射线屏蔽能力，并具备良好的抗压强度和高温力学性能。
