Method for preparing sintered wallboard from construction waste
The invention relates to the technical field of construction, and discloses a method for preparing a sintered wallboard from construction waste, and the method for preparing the sintered wallboard comprises the following steps: S1, carrying out mud-sand separation treatment on engineering residue soil to obtain washed sand and slurry; carrying out filter-pressing dehydration on the slurry by using a filter press to obtain a mud cake with the water content of less than 35%; s2, sorting and grinding the recycled aggregate obtained by treating the demolition waste to obtain red brick powder; s3, stirring and mixing the mud cake, red brick powder, bentonite and a plasticizer to obtain a mixture; and S4, the mixture is subjected to granulation, aging, extrusion molding, drying and sintering to prepare the sintered wallboard, compared with an existing ALC wallboard and a prefabricated concrete hollow wallboard, the sintered wallboard takes building waste as a main raw material, the problem that mud cakes and red brick recycled aggregates are difficult to dispose can be effectively solved, the microwave drying procedure is added in the drying process, and the production cost is reduced. The problem that a large-size green body is easy to crack when being dried in an existing muck sintered wallboard technology is solved.
本发明涉及建筑技术领域，且公开了一种建筑废弃物制备烧结墙板的方法，所述制备烧结墙板的方法包括以下步骤：S1、将工程渣土进行泥砂分离处理，得到水洗砂和泥浆；用压滤机对泥浆压滤脱水，得到含水率＜35％的泥饼；S2、将拆除废弃物处理得到的再生骨料，经过分拣、粉磨得到红砖粉末；S3、将泥饼、红砖粉末、膨润土、增塑剂进行搅拌混合得到混合料；S4、混合料经造粒、陈腐、挤出成型、干燥、烧结工艺制备出烧结墙板，与现有ALC墙板、预制混凝土空心墙板相比，烧结墙板以建筑废弃物为主要原材料，可以有效解决泥饼和红砖类再生骨料处置难的问题，在干燥工艺中增加微波干燥工序，解决了现有渣土烧结墙板技术中大尺寸坯体干燥易开裂的问题。
