Anti-radiation ultra-high performance concrete and preparation method thereof
The invention relates to the technical field of concrete, in particular to an anti-radiation ultra-high performance concrete and a preparation method thereof. The anti-radiation ultra-high performanceconcrete is prepared from the following components in parts by mass: 130-160 parts of micro-silica fume, 700-750 parts of cement, 150-200 parts of fly ash, 600-1200 parts of river sand, 50-800 partsof hematite, 180-200 parts of water, 40-50 parts of a water reducing agent and 130-170 parts of steel fibers. According to the invention, the crushed hematite is used for replacing the river sand in the concrete in proportion, so that the concrete with radiation protection and high strength is prepared, and the technical problems that the radiation protection concrete in the prior art is relatively low in strength and is easily damaged in the period of facing explosion impact are solved.
本发明涉及混凝体技术领域，具体涉及一种防辐射超高性能混凝土及其制备方法，以质量份数计，原料包括：微硅灰130‑160份、水泥700‑750份、粉煤灰150‑200份、河砂600‑1200份、赤铁矿50‑800份、水180‑200份、减水剂40‑50份、钢纤维130‑170份。本发明使用利用破碎后的赤铁矿，对混凝土中的河砂进行了比例替换，制备了一种具有防辐射并且拥有高强度的混凝土，克服现有技术中防辐射混凝土强度都比较低，在面临爆炸冲击的期间容易受到破坏的技术问题。
