2. Product description of Xinqiao gauge prestressed pipe grouting agent:
Prestressed pipe grouting agent
The grouting agent is: a micro-expansion grouting material mixed with ordinary cement. , compared with ordinary cement grouting materials, it has the characteristics of good fluidity, no bleeding, no delamination, full grouting, early strength, micro expansion, etc., and can be used for one-time grouting construction. The slurry in the pipe is dense and has no pores. Prestressed steel bars do not corrode and are firmly bonded to concrete.
Prestressed pipe grouting material
It is made of high-quality ordinary Portland cement and is compounded with grouting agent. It can be used by just adding water and stirring on site. The pipeline grouting material reduces the construction process of compounding the grouting agent with cement on site, especially avoiding the problems caused by the adaptability between the grouting agent and different cements. It is suitable for bonding and filling grouting of post-tensioned prestressed pipes and other small gaps that require high fluidity.

4. How to use grouting agent for new bridge gauge prestressed pipes
． The production of prestressed tendons, installation of anchors, clamps, etc., application of prestress, grouting, etc. should meet the design requirements and comply with the provisional technical conditions for prestressed concrete precast beams for passenger dedicated lines.
． The grouting agent is mixed into the cement with: (external mixing) and mixed evenly. The slurry can be used directly by adding water.
3. The reference water-cement ratio for mixing prestressed pipe pressure slurry cement slurry is. The actual amount of water added shall be based on the fluidity of the slurry.
． Prestressed pipes are pressed with slurry and water accurately weighed, and water is added strictly according to the determined water-cement ratio. The amount of water added is not allowed to be adjusted at will.
5. Packaging and storage of grouting agent for new bridge gauge prestressed pipes
． Packed in composite kraft paper, net weight/bag and/bag, shelf life is months
. It must be stored in a dry and ventilated room and be protected from moisture.
