Concrete co-doped with steel slag powder and fly ash and preparation method thereof
The invention discloses concrete doped with steel slag powder and fly ash and a preparation method of the concrete. The concrete is prepared from the following components in parts by weight: 205 to 225 parts of cement, 90 to 100 parts of mineral powder, 30 to 40 parts of fly ash, 30 to 40 parts of steel slag powder, 130 to 140 parts of water, 740 to 750 parts of sand, 940 to 960 parts of gravel and 5 to 6 parts of additive, the additive is a 301 water reducing agent; the fly ash is Huatai II-grade fly ash, the specific surface area is 420m < 2 >/kg, the ignition loss is 1.5%, the water content is 0.6%, the 7d activity index is greater than or equal to 60%, and the 28d activity index is greater than or equal to 75%; the fineness of the steel slag powder is less than or equal to 5%, the specific surface area is 280m < 2 >/kg, the 7d activity index is more than or equal to 60%, and the 28d activity index is more than or equal to 79% The invention has the advantages of simple preparation process, low labor cost, low carbon and environmental protection in production, and can greatly improve the utilization efficiency of solid waste resources when being applied to concrete.
本发明公开了一种复掺钢渣粉与粉煤灰的混凝土及其制备方法，包括：水泥为205‑225份、矿粉为90‑100份、粉煤灰为30‑40份、钢渣粉30‑40份、水为130‑140份、砂为740‑750份、碎石为940‑960份、外加剂为5‑6份；外加剂为301减水剂；粉煤灰为华太II级粉煤灰，比表面积为420m2/kg，烧失量为1.5％，含水率为0.6％，7d活性指数≥60％，28d活性指数≥75％；钢渣粉的细度≤5％，比表面积280m2/kg，7d活性指数≥60％,28d活性指数≥79％。根据本发明，具备制备工艺简单、工成本低、生产低碳环保的优点，应用到混凝土中能大幅提高固废资源的利用效率。
