Carbon fiber reinforced anti-radiation concrete and preparation method thereof
The invention relates to carbon fiber reinforced anti-radiation concrete and a preparation method thereof, and the carbon fiber reinforced anti-radiation concrete comprises the following raw materials by weight: 160-164 parts of water; 280 to 300 parts of cement; 45 to 65 parts of fly ash; 50-70 parts of mineral powder; 2000 to 2100 parts of broken iron ore; 1350 to 1450 parts of iron ore sand; 2.5 to 3.5 parts of a water reducing agent; 4-7 parts of carbon fiber; and 0.25 to 0.55 part of a dispersing agent. Compared with the prior art, the volume weight of the prepared carbon fiber reinforced radiation protection concrete is 3500-3900 kg/m < 3 >, the strength can meet the design requirement of C35 or above, and harmful rays can be effectively shielded. The carbon fibers form an interlaced net structure in the concrete, so that the mechanical property of the concrete can be improved, and the compression resistance and crack resistance of the concrete are further improved.
本发明涉及一种碳纤维增强防辐射混凝土及其制备方法，所述碳纤维增强防辐射混凝土，按重量份数计，由以下的原料组成：水160～164份；水泥280～300份；粉煤灰45～65份；矿粉50～70份；铁矿石碎石2000～2100份；铁矿石砂1350～1450份；减水剂2.5～3.5份；碳纤维4～7份；分散剂0.25～0.55份。与现有技术相比，本发明制备得到的碳纤维增强防辐射混凝土容重为3500‑3900kg/m3，且强度能够满足C35以上满足设计要求，可有效屏蔽有害射线。碳纤维在混凝土中形成交织网状结构，可以提高混凝土的力学性能，使混凝土的抗压与抗裂性能进一步提升。
