黑龙江省寒地建筑科学研究院研制成功的聚酯水泥粘结剂主要用于混凝土构件的修复、填隙、表面处理、新旧混凝土和砂浆的界面修补与粘结,可以取消传统的混凝土表面人工凿毛工序,不必做干燥处理。施工前只需将构件表面的浮尘、疏松物等清理干净即可,能有效地解决表层由 Heilongjiang Province Institute of Cold Building Science and Research successfully developed polyester cement binder is mainly used for repair of concrete structures, caulking, surface treatment, the interface between the old and new concrete repair and bonding, you can cancel the traditional artificial surface of concrete chisel Wool process, do not have to do the drying process. Before construction, it only needs to clean the surface dust, loose objects and so on, which can effectively solve the problem of surface layer
