Low-alkali plant-growing concrete based on steel slag and preparation method of low-alkali plant-growing concrete
The invention discloses low-alkali plant-growing concrete based on steel slag and a preparation method thereof, and relates to the technical field of building materials, the low-alkali plant-growing concrete comprises the following components in parts by mass: steel slag aggregate, steel slag powder, granulated blast furnace slag powder, gypsum, calcium aluminate, a reinforcing agent, a water reducing agent, a retarder and water, the recycled micro-powder composite expanding agent is prepared from the following components: 300 to 450 parts of steel slag aggregate, 20 to 30 parts of steel slag powder, 30 to 40 parts of granulated blast furnace slag powder, 15 to 20 parts of gypsum, 3 to 5 parts of calcium aluminate, 3 to 5 parts of reinforcing agent, 0.2 to 0.5 part of water reducing agent, 0.05 to 0.15 part of retarder and 25 to 35 parts of water. The process steps are relatively simple, and the steel slag, the mineral slag, the ardealite and the calcium aluminate are all from industrial by-products. The plant-growing concrete can be used for parts such as side slopes, roads, landscapes, central isolation belts and the like, and has the advantages of high strength, steel slag utilization rate of more than 80%, low alkalinity and rich low-concentration fertilizers and trace elements.
本发明公开了一种基于钢渣的低碱植生混凝土及其制备方法，涉及建筑材料技术领域，由以下组分组成：钢渣骨料、钢渣粉、粒化高炉矿渣粉、石膏、铝酸钙、增强剂、减水剂、缓凝剂、水，按质量份计，所述再生微粉复合膨胀剂由以下组分组成：钢渣骨料300‑450份、钢渣粉20‑30份、粒化高炉矿渣粉30‑40份、石膏15‑20份、铝酸钙3‑5份、增强剂3‑5份、减水剂0.2‑0.5份、缓凝剂0.05‑0.15份、水25‑35份，本发明的有益效果为：制备方法简单，可以采用常规的混凝土搅拌机现场搅拌施工，工艺步骤较为简单，钢渣、矿渣、磷石膏、铝酸钙均来源于工业副产物。植生混凝土可用于边坡、道路、景观、中央隔离带等部位，具有强度高、钢渣利用率达80%以上、碱度低，富含低浓度肥料和微量元素。
