Reactive powder concrete with large mixing amount of solid waste and preparation and use method of active powder concrete
The invention relates to active powder concrete with large mixing amount of solid waste and a preparation and use method of the active powder concrete. The active powder concrete comprises the following raw materials in parts by mass: 60-100 parts of a cementing material, 10 to 30 parts of fly ash, 1 to 10 parts of silica fume, 30 to 60 parts of granite saw mud, 80 to 160 parts of gold tailings, 0.02-0.05 part of an expanding agent, and high-strength fibers with a volumetric mixing amount of 0.5-2%. The method has the characteristics that a large amount of industrial solid waste is doped, the granite sawing mud with a large specific surface area and a certain activity index is used for replacing ground quartz powder, the gold tailing sand with high strength is used for replacing fine quartz sand as an aggregate, and a small amount of silica fume is used for filling accumulation pores of the granite sawing mud and the cementing material, so the prepared active powder concrete has the advantages of small particle accumulation porosity, high compactness, low preparation cost, high industrial waste resource utilization degree, environment friendliness, high strength, good external environment erosion resistance, simple preparation method and the like.
一种大掺量固体废弃物的活性粉末混凝土及制备使用方法，包括如下质量份数的原料：胶凝材料：60‑100份；粉煤灰：10‑30份；硅灰：1‑10份；花岗岩锯泥：30‑60份；金尾矿：80‑160份；膨胀剂：0.02‑0.05份，还包括体积掺量为0.5‑2％的高强纤维。本发明的特点掺入大量工业固体废弃物，采用比表面积大具有一定活性指数的花岗岩锯泥替代磨细石英粉，利用金尾矿砂强度高的特点，替代细石英砂作为骨料，少量硅灰填充花岗岩锯泥与胶凝材料堆积孔隙，制备的活性粉末混凝土颗粒堆积孔隙率小、密实度高、制备成本低、工业废弃物资源化利用程度高、环保、强度高、抗外界环境侵蚀性性能好、制备方法简单等优点。
