Cement-based polymer cementing material for duct piece repairing and duct piece repairing method
The invention provides a cement-based polymer cementing material for duct piece repairing and a duct piece repairing method. The material is prepared from the following components in percentage by weight: 55.5 to 58.8 percent of tailing slag; 30 to 35 percent of ordinary Portland cement; 8 to 10 percent of white cement; 0.9 to 1.2 percent of redispersible rubber powder; and 0.3 percent of cellulose ether. The duct piece repairing method comprises the following steps of: S1, estimating the total weight of a required cement-based polymer cementing material, and pouring the material into a container; S2, adding water into the container, the ratio of the cement-based polymer cementing material to the water being 1: 2.5, and stirring an obtained mixture until the mixture is fully wetted and uniform; S3, smearing/filling a to-be-repaired area with the mixture so as to complete the repairing of a duct piece. The material is high in setting and hardening speed and repairing strength; and the repairing method is simple and convenient and can shorten the waiting time of a repaired duct piece and increase the delivery speed of the duct piece.
本发明提出了用于管片修补的水泥基聚合物胶凝材料及管片修补方法，材料由以下组分按重量百分比配制而成：尾矿渣55.5～58.8％，普通硅酸盐水泥30～35％，白色水泥8～10％，可再分散性胶粉0.9～1.2％，纤维素醚0.3％。管片修补方法包括如下步骤：S1、估算所需的水泥基聚合物胶凝材料总重量，并将材料倒入容器中；S2、向容器中加入水，且水泥基聚合物胶凝材料与水的比例为1:2.5，搅拌至充分湿润均匀的混合物；S3、将混合物涂抹/填充至待修补区以完成管片的修补。本发明的材料凝结硬化速度快，修补强度高，修补方法简便，可以缩短管片修补后的等待时长，加快管片出厂速度。
