Radiation-proof concrete and preparation method thereof
The invention discloses radiation-proof concrete and a preparation method thereof. The radiation-proof concrete is prepared from the following raw materials in parts by weight: 15-30 parts of iron tailing powder, 5-10 parts of carbon nanotubes, 100-120 parts of gravel, 120-150 parts of sand, 50-70 parts of cement, 15-25 parts of nano silicon dioxide, 3-5 parts of a water reducing agent, 4-6 parts of carboxymethyl cellulose sodium and 120-160 parts of water. According to the concrete, by adding the iron ore powder, the carbon nano tubes, the nano silicon dioxide and the carboxymethyl cellulose sodium, all the raw material components can be fully and uniformly mixed, a conductive network can be formed, the concrete has an electromagnetic shielding function, and in addition, by adding the carbon nano tubes, the mechanical strength of the concrete can be effectively improved.
本发明公开了一种防辐射混凝土及其制备方法，所述防辐射混凝土包括如下重量份的原料：铁尾矿粉15～30份、碳纳米管5～10份、碎石100～120份、沙子120～150份、水泥50～70份、纳米二氧化硅15～25份、减水剂3～5份、羟甲基纤维素钠4～6份和水120～160份；本发明混凝土中通过铁矿石粉、碳纳米管、纳米二氧化硅和羟甲基纤维素钠的添加能够使得各原料组分充分混匀，并能够形成导电网络，使得混凝土具有电磁屏蔽功能，此外，碳纳米管的添加还能够有效提高混凝土的机械强度。
