Process for preparing sintered thermal insulation building block from sand washing mud
The invention relates to the field of building aggregate production, and discloses a process for preparing a sintered thermal insulation building block from sand washing mud. The process comprises a concentration procedure, a filter pressing procedure, a burdening procedure, an aging procedure, a forming procedure, a drying procedure and a sintering procedure. The process has the beneficial effects that the emission of wastes such as mud generated in sand washing production can be reduced; shale and other raw materials needing to be mined in traditional brick making are not used, and resourcesare saved; additives are added during forming, and the compressive strength after curing forming is improved by 6% or above compared with the compressive strength without addition of the additives; the sintered heat preservation building block prepared by the invention has a heat preservation function, and the heat conductivity coefficient is less than 0.4 W/m.K; the sintered heat preservation building block prepared by the method is small in apparent density which is less than 900kg/m < 3 >, and the dead weight is saved by more than 50% compared with that of the traditional brick.
本发明公开了一种洗砂泥制烧结保温砌块工艺，涉及建筑骨料生产领域，包括浓缩工序、压滤工序、配料工序、陈腐工序、成型工序、干燥工序和烧成工序。本发明的有益效果为：本发明有助于减少洗砂生产中产生的泥等废弃物的排放；本发明不用传统的制砖所需开采的页岩等原料，节约资源；本发明在成型时加入了添加剂，固化成型后抗压强度比不添加提高6％以上；本发明制得的烧结保温砌块具有保温功能，导热系数小于0.4W/m.K；本发明制得的烧结保温砌块表观密度小，小于900kg/m3，比传统砖节约50％以上自重。
