Method for preparing concrete slab by recycling waste stone
The invention discloses a method for preparing a concrete plate by recycling waste stone, and relates to the technical field of concrete plates. The concrete comprises the following raw materials in parts by weight: ordinary Portland cement, recycled aggregate, fly ash, silica fume, an additive, a water reducing agent and water, when the additive in the concrete plate is prepared, graphene oxide is reduced to obtain reduced graphene oxide, sulfanilic acid and sodium nitrite react to generate aryl diazonium salt, and the aryl diazonium salt and the reduced graphene oxide react to obtain sulfonated graphene; enabling sulfonated graphene, zirconium oxychloride octahydrate and titanium tetrachloride to react to prepare an additive; according to the admixture prepared by the invention, the structural strength, the service life, the self-cleaning capability and the environmental adaptability of the concrete plate are remarkably improved, and the application potential of the admixture in the fields of buildings and engineering is widened.
本发明公开了一种废旧石材回收再生制备混凝土板材的方法，涉及混凝土板材的技术领域。本发明包括以下按重量份计原料，普通硅酸盐水泥、再生骨料、粉煤灰、硅灰、外加剂、减水剂、水；本发明在制备混凝土板材中的外加剂时，将氧化石墨烯进行还原得到还原氧化石墨烯，通过对氨基苯磺酸和亚硝酸钠反应应生成芳基重氮盐，芳基重氮盐和还原氧化石墨烯反应得到磺化石墨烯；将磺化石墨烯、八水合氯氧化锆和四氯化钛反应制得外加剂；本发明制得的外加剂使得混凝土板材在结构强度、使用寿命、自清洁能力以及环境适应性方面得到了显著提升，拓宽了其在建筑和工程领域的应用潜力。
