Rapid repair material for concrete pavement
The invention relates to the field of concrete repairing materials, and particularly discloses a rapid repairing material for a concrete pavement. The rapid repair material for the concrete pavement comprises Portland cement, quartz sand, modified polymer rubber powder, a superplasticizer, an early strength agent, an expanding agent and fly ash. The modified high-molecular rubber powder is prepared by modifying high-molecular water-soluble rubber powder with a silane coupling agent, butanetetracarboxylic acid, hydroxypropyl methyl cellulose and organic silicon modified acrylic resin; the preparation method comprises the following steps: S1, preparing the aggregate, S2, stirring the expanding agent and the modified polymer rubber powder in a stirrer, adding the early strength agent triethanolamine in the stirring process, and uniformly mixing with the aggregate to obtain the repair material. The rapid repairing material composition for the concrete pavement can be used for repairing the concrete pavement, and has the advantage of relatively high viscosity; in addition, the preparation method has the advantage of being easy to operate.
本申请涉及混凝土修复材料领域，具体公开了一种混凝土路面快速修复材料。混凝土路面快速修复材料包括硅酸盐水泥，石英砂，改性高分子胶粉，高效减水剂，早强剂，膨胀剂，粉煤灰；所述改性高分子胶粉是高分子水溶性胶粉通过硅烷偶联剂、丁烷四羧酸、羟丙基甲基纤维素和有机硅改性丙烯酸树脂改性制得；其制备方法为：S1:制备骨料，S2：将膨胀剂和改性高分子胶粉置于搅拌机中搅拌，搅拌过程中加入早强剂三乙醇胺，与骨料混合均匀后即得修复材料。本申请的混凝土路面快速修复材料该组合物可用于修补混凝土路面，其具有粘性较强的优点；另外，本申请的制备方法具有容易操作的优点。
