Neutron radiation prevention boron carbide concrete and preparation method thereof
The invention discloses neutron radiation prevention boron carbide concrete and a preparation method thereof. The neutron radiation prevention boron carbide concrete comprises the following components in parts by weight: 383 parts of fine aggregate; 1142 parts of coarse aggregate; 175 to 180 parts of water; a water reducing agent the weight of which is 1%-1.2% of that of a gel material; 295 to 325 parts of cement; 46 parts of fly ash; 86 parts of slag powder; 220 to 300 parts of boron carbide. The method comprises the following steps: sequentially pouring the coarse aggregate, the fine aggregate, the fly ash and the slag powder into a stirring tank; sequentially pouring boron carbide and cement into the stirring tank; starting the stirring tank, and stirring for a second set time; pouring the water and the water reducing agent into the stirring tank; starting the stirring tank, and continuously stirring according to a set stirring speed for a third set time. The boron carbide is used as a shielding and control material of the concrete, so that the volume weight of the concrete can be reduced on the premise of ensuring the radiation protection performance of the concrete under the condition of using conventional fine aggregate and coarse aggregate, and the concrete can be ensured to have relatively good flowability and pumpability.
本发明公开了一种防中子辐射碳化硼混凝土及其制备方法，包括以下重量份的组分：细骨料：383份；粗骨料：1142份；水：175～180份；减水剂，其重量为为凝胶材料的1％～1.2％；水泥：295～325份；粉煤灰：46份；矿渣粉：86份；碳化硼：220～300份；方法包括将粗骨料、细骨料、粉煤灰和矿渣粉依次倒入搅拌罐内；将碳化硼、水泥依次倒入搅拌罐内；启动搅拌罐，搅拌第二设定时间；将水和减水剂倒入搅拌罐内；启动搅拌罐，按照设定的搅拌速度和第三设定时间持续搅拌；通过将碳化硼作为混凝土的屏蔽和控制材料，在使用常规细骨料和粗骨料的情况下，可以达到在保障其防辐射性能的前提下，减小混凝土的容重，够保障混凝土具有较好的流动性及可泵性能。
