Lightweight concrete prefabricated wallboard and preparation method thereof
The invention discloses a lightweight concrete prefabricated wallboard and a preparation method thereof, and the preparation method comprises the following steps: S1, cement, fly ash, silicon carbide powder, dihydrate gypsum and water are uniformly mixed to obtain a mixed gel material; s2, uniformly mixing the mixed gel material, aluminum oxide hollow spheres and tetramethyl orthosilicate modified polyester fibers to obtain a base material; s3, adding polyacrylamide rosin ketone, methacrylic acid phosphoric acid and 2-acrylamide-2-methylpropanesulfonic acid into the base material, and uniformly mixing to obtain concrete mortar; s4, the mortar is put into a wallboard forming mold, forming and demolding are conducted, and then a lightweight concrete wallboard blank is obtained; and S5, the lightweight concrete wallboard blank is subjected to conventional curing, and the lightweight concrete wallboard is obtained. According to the invention, the material source of the lightweight concrete prefabricated wallboard is newly increased, resource utilization of ceramic wastes including polishing wastes is realized, and the prepared product has the advantages of light weight and good mechanical properties.
本发明公开了一种轻质混凝土预制墙板及其制备方法，所述制备方法可包括以下步骤：S1、将水泥、粉煤灰、碳化硅粉体、二水石膏和水混合均匀，得到混合凝胶材料；S2、将混合凝胶材料、氧化铝空心球和正硅酸甲酯改性聚酯纤维混合均匀，得到基材；S3、向基材中加入聚丙烯酰胺松香酮、甲基丙烯酸磷酸和2‑丙烯酰胺‑2‑甲基丙磺酸混合均匀，得到混凝土砂浆；S4、将砂浆放入成型墙板模具中，成型、脱模后得到轻质混凝土墙板坯体；S5、将轻质混凝土墙板坯体进行常规养护，得到轻质混凝土墙板。本发明新增轻质混凝土预制墙板的材料来源，实现含抛光废料在内的陶瓷废弃物的资源化利用，制备出的产品具有轻质和力学性能佳的优点。
