The raw material of prestressed plastic corrugated pipe is. Its corrosion resistance is far better than that of metal. It is not afraid of acid and alkali corrosion. It does not corrode itself and can effectively protect the prestressed tendons from corrosion. Many prestressed structures are exposed to severe external influences, such as de-icing salts or brine. When post-tensioned members leak water due to micro-cracks in the waterproofing layer and blockage or failure of drainage facilities, the prestressed tendons may be subject to corrosion. The Construction Guidelines for Grouting of Prestressed Tendons state that metal pipes have no permanent corrosion resistance and are not sufficient to resist water leakage and reaching the grout as well as the prestressed tendons. Prestressed plastic corrugated pipes can provide a barrier protection function for prestressed tendons that is far superior to metal corrugated pipes, and can prevent harmful substances from penetrating the pipeline and contaminating it, thereby ensuring better durability of the post-tensioned prestressed structure. Prestressed plastic corrugated pipe is a raw material and a new type of hole-forming material. It is mainly used in post-tensioned prestressed cement structures and tie rod holes. It has good sealing and no water leakage
Slurry
Ring stiffness, high friction parameters, small resistance to aging, resistance to electrical erosion, good elasticity, and not easy to be chipped by tamping rods. The advantages of breaking and new connection methods make construction connection more convenient. When the hole-forming material is damaged, the paddle is the last protective barrier for the prestressed steel plate in the prestressed cement structure.
