Preparation method of C10-C40 phosphate tailing artificial aggregate concrete
The invention discloses a preparation method of C10-C40 phosphate tailing artificial aggregate concrete. The phosphate tailing aggregate concrete comprises 600 kg/m < 3 > to 700 kg/m < 3 > of phosphate tailing aggregate, 400 kg/m < 3 > to 500 kg/m < 3 > of natural gravel, 300 kg/m < 3 > to 400 kg/m < 3 > of machine-made sand, 200 kg/m < 3 > to 300 kg/m < 3 > of river sand, 220 kg/m < 3 > to 450 kg/m < 3 > of a modifier and 5 kg/m < 3 > to 11 kg/m < 3 > of a reinforcing agent, the water-binder ratio is 0.3-0.9, the volume weight of the concrete is 2270 kg/m < 3 > to 2350 kg/m < 3 >, the slump is 70 mm to 180 mm, and the sand ratio is 25% to 35%. According to the present invention, the existing industrial solid waste phosphorus tailings are adopted, the artificial aggregate prepared from the high-doping-amount phosphorus tailings is adopted to replace the natural crushed stone, and the C10-C40 different-strength-grade phosphorus tailing artificial aggregate concrete is prepared from the phosphorus tailing artificial aggregate, the natural crushed stone, the mixed sand, the modifier, the reinforcing agent and the water so as to prepare the C10-C40 different-strength-grade phosphorus tailing artificial aggregate concrete,
本发明公开了一种C10‑C40磷尾矿人造骨料混凝土的制备方法。磷尾矿骨料混凝土中磷尾矿骨料600 kg/m3~700 kg/m3，天然碎石400 kg/m3~500 kg/m3，机制砂300 kg/m3~400 kg/m3，江砂200 kg/m3~300 kg/m3，改性剂220 kg/m3~450 kg/m3，增强剂5 kg/m3~11 kg/m3，水胶比0.3~0.9，其中混凝土容重2270 kg/m3~2350 kg/m3，塌落度70 mm~180mm，砂率25%~35%。本发明现有工业固体废料磷尾矿，用大掺量磷尾矿制备的人造骨料代替天然碎石，通过磷尾矿人造骨料、天然碎石、混合砂，改性剂，增强剂和水制备C10‑C40不同强度等级磷尾矿人造骨料混凝土。
