Lithium slag-based unfired lightweight aggregate and preparation method thereof
The embodiment of the invention provides a lithium slag-based unfired lightweight aggregate and a preparation method thereof. The raw materials of the lithium slag-based unfired lightweight aggregate comprise a raw material and water, and the raw material comprises the following components in percentage by mass: 25-60% of lepidolite slag, 10-50% of solid waste and 5-40% of cement; the lepidolite slag comprises aluminosilicate and harmful elements such as fluorine, beryllium and thallium; the solid waste comprises the following components in percentage by mass: 10-70% of silicon dioxide, 2-30% of aluminum oxide and 10-60% of calcium oxide. Harmful elements in the lithium slag-based unfired lightweight aggregate are stably cured, the cylinder compressive strength is relatively high, the water absorption rate is relatively low, and the density is adjustable. The preparation cost is low, the production process is simple, large-scale production is easy, and the material can be applied to the fields of roadbed materials, building materials and the like.
本申请实施例提供一种锂渣基免烧轻集料及其制备方法。本申请的锂渣基免烧轻集料的原料包括生料和水，生料按质量分数计，包括25%~60%的锂云母渣、10~50%的固废和5%~40%的水泥；锂云母渣包括铝硅酸盐以及氟、铍、铊有害元素；固废的组分按质量份数计，包括10%~70%二氧化硅，2%~30%氧化铝、10%~60%氧化钙。本申请的锂渣基免烧轻集料中的有害元素实现稳定固化，筒压强度较高，吸水率也较低，密度可调节。且制备成本低，生产工艺简单，易于大规模生产，可应用于路基材料、建材材料等领域。
