Mud-jacking Material for Spiral Tube

Brief Introduction
1. Mud-jacking Material for Spiral Tube, a kind of waterproof material for railway post-tensioned concrete beam tube
2. It is made by cement, high effective water reducing agent, extender and other materials through drying mixing, and then mixed with water in a fixed proportion

Features
1. High liquidity and groutability for compact filling
2. High workability
3. No bleeding, allowing no void or bubble
4. No shrinkage, slight distensibility, compact structure after solidification
5.Not contain any additive which has corrosion action upon prestressed reinforcement, like high-alkali extender

Applications
1. Applicable to grouting of railway post-tensioned concrete beam tube
2. Suited for grouting of large scale prestressed structure and arm mooring of earth anchorage system
