Iron tailing lightweight phase change concrete and preparation method thereof
The invention discloses iron tailing lightweight phase change concrete and a preparation method thereof, belonging to the technical field of building materials. The invention aims to solve the problems of high cost and poor temperature adjustment effect of phase change temperature adjustment concrete, poor stability of iron tailings, dry shrinkage cracking, high maintenance cost and the like in the prior art. The iron tailing lightweight phase change concrete is prepared from the following raw materials in parts by mass: 5 to 15 parts of cement, 10 to 20 parts of quick lime, 10 to 15 parts of fly ash, 35 to 45 parts of river sand, 30 to 40 parts of iron tailings, 0.08 to 0.15 part of aluminum powder paste, 0.2 to 0.5 part of water-absorbent resin, 0.2 to 0.8 part of an active auxiliary agent, 55 to 65 parts of water and 0.1 to 0.5 part of a water reducing agent. The iron tailing lightweight phase change concrete provided by the invention has good workability and good constructability in a preparation process; collapsing can be effectively prevented in early-stage maintenance; maintenance conditions are simple, and hydration reaction can be continued; stability is good, and cracking is prevented; heat is effectively absorbed and a temperature is reduced when a fire disaster occurs; and a temperature can be adjusted according to humidity to keep a comfortable environment.
本发明公开了一种铁尾矿轻质相变混凝土及其制备方法，属于建筑材料技术领域，解决现有技术中相变调温混凝土成本高昂，调温效果不佳，铁尾矿安定性不良，干缩开裂，养护成本高等问题。本发明的铁尾矿轻质相变混凝土由包括以下质量份的原料制成：水泥5‑15份、生石灰10‑20份、粉煤灰10‑15份、河沙35‑45份、铁尾矿30‑40份、铝粉膏0.08‑0.15份、吸水树脂0.2‑0.5份、活性助剂0.2‑0.8份、水55‑65份、减水剂0.1‑0.5份。本发明提供的铁尾矿轻质相变混凝土在制备过程中有很好的和易性，施工性好；在前期养护中可有效防止坍缩；养护条件简单，能持续水化反应；安定性好，预防开裂；在发生火灾时有效吸热，降低温度；能根据湿度调节温度保持舒适环境。
