Manufacturing method of special lightweight aggregate concrete for graphite tailing and biomass straw composite wallboard
The invention discloses a manufacturing method of special lightweight aggregate concrete for graphite tailing and biomass straw composite wallboards, and belongs to the field of building materials. The method comprises the following steps: 1, pretreating the graphite tailings and the biomass straws; 2, taking general-purpose Portland cement, pretreated biomass straws, pretreated graphite tailings, coal-fired furnace slag and a special additive as raw materials; and 3, adding the raw materials into a stirrer, uniformly mixing, adding water, and continuously stirring. The invention develops a new way of the biomass straws and the graphite tailings in the aspect of comprehensive utilization of resources, and provides a reasonable matching mode and proportion of the graphite tailings and the biomass straws. The raw materials are low in price, and low-cost solid wastes are used for replacing natural sand raw materials, so that the economic benefits are obvious and prominent. The wallboard made of the special lightweight aggregate concrete disclosed by the invention meets performance indexes in Technical Requirements for Wallboards for Fabricated Building (JG/T578-2021); and the thermal insulation performance is superior to the current national standard requirement.
一种石墨尾矿、生物质秸秆复合墙板专用轻集料混凝土的制作方法，它属于建筑材料领域。方法：一、石墨尾矿和生物质秸秆进行预处理；二、取通用硅酸盐水泥、预处理后生物质秸秆、预处理后石墨尾矿、燃煤炉渣和专用外加剂作为原料；三、原料加到搅拌机中混匀，加水，继续搅拌即完成。本发明开发了生物质秸秆、石墨尾矿在资源综合利用方面的新途径，提出石墨尾矿、生物质秸秆使用的合理配合方式和比例。原料价格低廉，利用低成本的固废代替天然砂原材料由此产生的经济效益明显、突出。本发明专用轻集料混凝土制作的墙板满足《装配式建筑用墙板技术要求》(JG/T578－2021)中的性能指标；其隔热保温性能优于现行国家标准要求。
