Rapid concrete repairing material doped with fine coal gasification coarse slag, and preparation method and application thereof
The invention belongs to the technical field of building materials, and particularly relates to a fine coal gasification coarse slag doped concrete rapid repairing material and a preparation method and application thereof. The fine coal gasification coarse slag doped concrete rapid repairing material is prepared from the following raw materials: fine coal gasification coarse slag, a cementing material, a composite retarder, metakaolin and natural sand, the preparation method comprises the following steps: step 1, mixing ground coal gasification coarse slag, dead burned magnesium oxide, monopotassium phosphate, anhydrous calcium acetate, boric acid and metakaolin to obtain a first mixture; step 2, adding water into the first mixture, and uniformly stirring at a low speed to obtain a second mixture; and step 3, adding natural sand into the second mixture, and uniformly stirring at a high speed, thereby obtaining the product. The invention also discloses an application of the concrete rapid repairing material doped with the fine coal gasification coarse slag in pavement disease maintenance. According to the invention, the fine coal gasification coarse slag is utilized to slow down the gelling reaction process of the magnesium phosphate cement, inhibit the bad heat effect in the gelling process and coordinate the visual effect of the interface of new and old materials.
本发明属于建筑材料技术领域，具体涉及掺磨细煤气化粗渣混凝土快速修补材料及制备方法与应用。所述掺磨细煤气化粗渣混凝土快速修补材料包括如下原料：磨细煤气化粗渣、胶凝材料、复合缓凝剂、偏高岭土和天然砂；所述制备方法包括：步骤1，将磨细煤气化粗渣、重烧氧化镁、磷酸二氢钾、无水乙酸钙、硼酸和偏高岭土混合，得第一混合物；步骤2，向第一混合物中加水并低速搅拌均匀，得第二混合物；步骤3，向第二混合物中加入天然砂并高速搅拌均匀，即得；还公开了掺磨细煤气化粗渣混凝土快速修补材料在路面病害维修中的应用。本发明利用磨细煤气化粗渣减缓磷酸镁水泥的胶凝反应进程，抑制胶凝过程不良的热效应，并协调新旧材料界面的视觉效果。
