Phosphogypsum solid waste high-strength concrete
The invention discloses ardealite solid waste high-strength concrete. The high-strength concrete is prepared from the following components in parts by weight: 70 to 100 parts of phosphogypsum, 40 to 80 parts of hydroxyethyl methacrylate phosphate, 20 to 30 parts of zeolite powder, 20 to 40 parts of polypropylene fiber, 150 to 200 parts of ordinary Portland cement, 20 to 40 parts of modified calcium oxide, 10 to 30 parts of silicon dioxide modified acrylate, 5 to 15 parts of modifier and 8 to 18 parts of enhancer. According to the prepared high-strength concrete, large-scale resource utilization of industrial solid wastes such as ardealite is achieved, no natural mineral resources are consumed during preparation, in addition, the prepared concrete is excellent in overall compression resistance and corrosion resistance, the service life of the concrete is greatly prolonged, and economic benefits are increased.
本发明公开了一种磷石膏固体废料高强度混凝土，高强度混凝土组分按重量份数包括磷石膏70‑100份、羟乙基甲基丙烯酸酯磷酸酯40‑80份、沸石粉20‑30份、聚丙烯纤维20‑40份、普通硅酸盐水泥150‑200份、改性氧化钙20‑40份、二氧化硅改性丙烯酸酯10‑30份、改性剂5‑15份和增强剂8‑18份，本发明制备工艺简单，制得的高强度混凝土，实现了磷石膏等工业固废的大规模资源化利用，且制备时不消耗任何天然矿产资源，此外制得的混凝土整体抗压、耐腐蚀性能优越，大大延长了混凝土的使用寿命，增进了经济效益。
