Mine fine tail mud-based unfired lightweight aggregate and preparation method thereof
The invention relates to a mine fine tail mud-based unfired lightweight aggregate and a preparation method thereof. The mine fine tail mud-based unfired lightweight aggregate comprises the following components in parts by mass: 50-450 parts of mine fine tail mud, 50-100 parts of light sand, 550-950 parts of cement, 0.5-18 parts of an additive and 200-250 parts of water, wherein the additive is a mixture of sodium bicarbonate and ammonium bicarbonate; the mass ratio of sodium bicarbonate to ammonium bicarbonate is (5-9): (1-5). The preparation method of the mine fine tail mud-based unfired lightweight aggregate comprises the following steps: carrying out microwave medium-high fire heating treatment on mine fine tail mud; and the lightweight aggregate is subjected to preservative film covering maintenance, maintenance under the environment with the relative humidity of 20%-35% and carbon dioxide maintenance. According to the invention, comprehensive utilization of the mine fine tail mud can be realized, and the prepared lightweight aggregate has the advantages of light weight, high strength and low water absorption, and has good application prospects.
本发明涉及一种矿山细尾泥基免烧轻骨料及其制备方法，所述矿山细尾泥基免烧轻骨料包括质量份数如下的组分：矿山细尾泥50‑450份、轻砂50‑100份、水泥550‑950份、添加剂0.5‑18份、水200‑250份；其中，所述添加剂为碳酸氢钠和碳酸氢铵混合物；所述碳酸氢钠和碳酸氢铵的质量比为(5‑9):(1‑5)。所述矿山细尾泥基免烧轻骨料的制备方法包括：对矿山细尾泥进行微波中高火加热处理；对轻骨料进行覆保鲜膜养护、相对湿度20％‑35％的环境下养护、二氧化碳养护。本发明可实现矿山细尾泥的综合利用，所制备的轻骨料具有质量轻、强度高、吸水率低的优点，具有良好的应用前景。
