| Abstract: | The effect of grouting of the ducts in the prestressed concrete structures is directly related to the corrosion of the prestressed reinforcement bars. By means of vacuum-assisted grouting, the ducts can be tightly filled with grout, thereby the problem of corrosion of the reinforcement bars can be well resolved. In the article, taking the grouting practice in Changchun-Huichun Highway Project as example, the author makes art elaboration on the principle, technical process and quality control of vacuum-assisted grouting. |
