Radiation-proof concrete and preparation method thereof
The invention relates to radiation-proof concrete and a preparation method thereof, and the radiation-proof concrete comprises the following components in parts by weight: 1900-2200 parts of iron ore coarse aggregate, 1200-1500 parts of iron ore fine aggregate, 250-300 parts of ordinary cement, 40-70 parts of fly ash, 50-70 parts of mineral powder, 1.5-3.5 parts of a water reducing agent, 3-4 parts of short carbon fiber and 162 parts of water. The apparent density of the anti-radiation concrete is 3060 to 4000 kg/m < 3 >. Compared with the prior art, the iron ore is adopted as the coarse and fine aggregate, the iron ore has high strength and high density, and the shielding capacity of the anti-radiation concrete on gamma rays and neutron rays can be effectively improved as the coarse and fine aggregate of the anti-radiation concrete; the short carbon fibers are doped into the radiation-proof concrete, so that the iron ore is effectively prevented from sinking to the bottom, the mechanical property of the radiation-proof concrete is improved, and the splitting tensile property of the radiation-proof concrete is improved.
本发明涉及一种防辐射混凝土及其制备方法，按照重量份计，包括以下各组分：铁矿石粗骨料1900‑2200份、铁矿石细骨料1200‑1500份、普通水泥250‑300份、粉煤灰40‑70份、矿粉50‑70份、减水剂1.5‑3.5份、短切碳纤维3‑4份以及水162份。所述防辐射混凝土的表观密度为3060‑4000kg/m3。与现有技术相比，本发明采用铁矿石作为粗细骨料，铁矿石自身具有高强度和高密度，作为防辐射混凝土的粗细骨料能有效提升防辐射混凝土对γ射线和中子射线的屏蔽能力；采用短切碳纤维掺入防辐射混凝土内，有效防止铁矿石沉底，提高防辐射混凝土的力学性能，提高防辐射混凝土的劈裂抗拉学性能。
