Iron tailing aggregate UHPC and preparation method thereof
The invention discloses an iron tailing aggregate UHPC (Ultra High Performance Concrete) and a preparation method thereof, and belongs to the technical field of concrete production technologies. According to the technical scheme, the iron tailing aggregate is characterized by comprising the following components: iron tailing sand with six grades of particle sizes of 25-27 mm, 18-20 mm, 15-17 mm, 8-10 mm, 4-5 mm and 2-3 mm; the mass percent of each grade of iron tailing sand is respectively 4-6%, 18-22%, 24-26%, 24-26%, 18-22% and 4-6%, so that the void ratio of the aggregate can be obviously reduced, the compactness of the iron tailing aggregate is higher, and the effect of enhancing the corrosion resistance of the iron tailing aggregate is achieved. The invention further discloses the iron tailing aggregate UHPC which comprises the iron tailing aggregate, and the corrosion resistance, the falling resistance and the durability of concrete are enhanced.
本发明公开了铁尾矿骨料UHPC及其制备方法，属于混凝土生产技术的技术领域。其技术方案要点是铁尾矿骨料，包括有以下组分：粒径为25‑27mm、18‑20mm、15‑17mm、8‑10mm、4‑5mm和2‑3mm六种级配的铁尾矿砂；所述各级配铁尾矿砂的质量百分比分别为4‑6％、18‑22％、24‑26％、24‑26％、18‑22％和4‑6％，可以明显减少骨料的空隙率，使铁尾矿骨料密实度更高，达到了增强了铁尾矿骨料的耐腐蚀性能的效果。本发明还公开了一种铁尾矿骨料UHPC，包括上述的铁尾矿骨料，增强了混凝土的耐腐蚀性、抗摔性和耐久性。
