High-strength copper tailing ceramsite and preparation method thereof
The invention relates to high-strength copper tailing ceramsite and a preparation method thereof, and the ceramsite is prepared from the following raw materials in percentage by weight: 90-100% of copper tailings and 0-10% of fly ash. The preparation process comprises the following steps: drying the copper tailings raw material in the sun, screening, drying to constant weight, weighing the copper tailings and the fly ash according to the mixing ratio, uniformly mixing the dry materials, adding water, uniformly stirring, manually balling, granulating, drying in a drying oven for 24 hours, putting into a high-temperature electric furnace, preheating, roasting, and cooling to obtain the copper tailings ceramsite. The bulk density, apparent density, void ratio, water absorption rate and cylinder compressive strength of the lightweight aggregate meet the requirements of GBT 174311-2010 Lightweight Aggregate and Test Method thereof. According to the preparation method disclosed by the invention, the selection standard of ceramsite preparation raw materials is reduced, the stacking density, cylinder compressive strength and the like of the fired ceramsite are far beyond the standard of lightweight aggregate, and the ceramsite can be used as coarse aggregate for preparing concrete.
本发明涉及一种高强铜尾矿陶粒及其制备方法，其中，制备陶粒的原材料配比为：铜尾矿90%~100%，粉煤灰0%~10%；制作工艺流程为：将铜尾矿原料晒干，进行筛分，然后烘干至恒重，再按照配合比对铜尾矿和粉煤灰称量，将干料混合均匀后，加入水搅拌均匀，然后手工搓球造粒，再放入烘箱中烘干24h，之后放入高温电炉中，经过预热，焙烧，冷却，制得铜尾矿陶粒，其堆积密度，表观密度，空隙率，吸水率，筒压强度都满足GBT 174311‑2010《轻集料及其试验方法》要求。本发明的制备方法降低了陶粒制备原料的选择标准，烧制出的陶粒的堆积密度、筒压强度等远远超出轻集料标准，能够作为粗骨料制备混凝土。
