Hole grouting agent - grouting material manufacturer produces and sells itself, with favorable price and quality assurance

Manufacturer's contact number Xiao Cui
Grouting material is a product specially used for grouting construction of post-tensioned prestressed pipes (holes). It is optimized and formulated with a variety of high-quality cement-based materials and high-performance admixtures. It has excellent It has the characteristics of fluidity, stable slurry, good filling, adjustable setting time, no shrinkage, micro-expansion, high strength, and no harmful substances to steel bars.

Application purpose
Manufacturer’s contact number Xiao Cui
Protect the prestressed tendons from corrosion and ensure the safety of the prestressed structure
Ensure that the prestressed tendons are in contact with the concrete The bonding force between them allows the prestressing force between them to be effectively transmitted, allowing the prestressed tendons and concrete to work together.
Eliminate fatigue damage to anchors caused by stress changes in prestressed concrete structures under repeated loads, extend the service life of anchors, and improve the reliability of the structure.

Application fields
Various railway and highway post-tensioned prestressed bridge tunnel grouting.
Grouting of large prestressed structural channels.
Leak-proof grouting at joints of various concrete structures.
Curtain grouting, anchor grouting, gap filling or repair, etc.
Construction Points
The water-to-material ratio can be adjusted according to different grouting parts.
First add the actual mixing water into the mixer, start the mixer, add all the slurry evenly, and stir while adding. After all the powder is added, stir quickly, add the remaining mixing water, and continue stirring.
The duration of the grouting material from stirring to pressing into the hole depends on the temperature, and is generally within the range of ~.
The slurry should be continuously stirred before use and during the injection process to maintain the uniformity and fluidity of the slurry.
When grouting, a piston pressure pump or vacuum pump should be used, and the pressure must be greater than
When grouting, the temperature of the slurry should be maintained between ℃ and ℃, otherwise measures should be taken to meet the conditions.
Precautions
The mixer speed should not be lower than /.
For cement slurries whose fluidity has been reduced due to delayed use, water must not be added to increase their fluidity.
During construction, under high temperature conditions, a time with lower temperatures should be selected. If construction is performed at night under low temperature conditions, winter construction standards should be followed.
Packaging and Storage
Packed in double-layer composite bags, net weight kg/bag, shelf life is one month. If used beyond the expiration date, it must be tested and verified before use.
Avoid direct sunlight, pay attention to moisture and damage to the packaging, and store it on a pallet off the ground in a dry and ventilated room.
