Freeze-thaw resistant iron tailing foam concrete and preparation method thereof
The invention discloses freeze-thaw resistant iron tailing foam concrete and a preparation method thereof. The freeze-thaw resistant iron tailing foam concrete is prepared from the following raw materials in parts by weight: 30-45 parts of iron tailing powder, 40-65 parts of cement, 5-15 parts of fly ash, 25-50 parts of water, 1-2 parts of a foaming agent, 0.5-1 part of polypropylene fiber, 1-1.5 parts of a water reducing agent and 0.05-0.1 part of a foam stabilizer, wherein the water reducing agent is a self-made polycarboxylic acid type high-efficiency water reducing agent. The anti-freezing and thawing performance of the iron tailing powder foam concrete is greatly improved by double doping of the polycarboxylate superplasticizer and the polypropylene fiber, and a new way is opened up for comprehensive utilization of the iron tailing powder.
本发明公开了一种具有抗冻融性的铁尾矿泡沫混凝土及其制备方法，包括以下重量份原料制成：铁尾矿粉30‑45份、水泥40‑65份、粉煤灰5‑15份、水25‑50份、发泡剂1‑2份、聚丙烯纤维0.5‑1份、减水剂1‑1.5份、稳泡剂0.05‑0.1份，所述减水剂为自制聚羧酸系高效减水剂。本发明将聚羧酸系高效减水剂和聚丙烯纤维双掺大大提高了铁尾矿粉泡沫混凝土的抗冻融性能，为铁尾矿粉的综合利用开辟了新的途径。
