一种低硅铁尾矿蒸压砖及其制备方法
摘要：
本发明提出一种低硅铁尾矿蒸压砖，由下述原料制得：主料、石膏和水；石膏占主料的质量百分比为1％，水占主料的质量百分比为15％；主料包括的原料及质量百分比为：低硅铁尾矿65％～75％、黄沙15％～20％、石灰10％～15％，低硅铁尾矿、黄沙和石灰所占质量百分比之和为100％。还公开了该低硅铁尾矿蒸压砖的制备方法。本发明工艺简单，生产成本低，使低硅铁尾矿资源得到再生利用，减轻尾矿对环境的污染，且制备的蒸压砖成本低、强度高，具有较高的经济效益。
摘要（英）：

The invention provides a low silicon iron tailing autoclaved brick.The low silicon iron tailing autoclaved brick is prepared from main materials, gypsum and water, wherein gypsum accounts for 1% of the main materials by mass, and water accounts for 15% of the main materials by mass.The main materials include, by mass, 65-75% of low silicon iron tailings, 15-20% of yellow sand and 10-15% of lime, and the total mass percentage of low silicon iron tailings, yellow sand and lime is 100%.The invention further discloses a preparing method of the low silicon iron tailing autoclaved brick.The technology is simple, production cost is low, low silicon iron tailing resources are recycled, and pollution of tailings to the environment is relieved; besides, the prepared autoclaved brick is low in cost and high in strength and has high economic benefits.
