>High-strength non-shrinkage grouting material is a cement-based Self-flowing micro-expansion dry mortar has the characteristics of early strength, high strength, self-flow and micro-expansion. It is suitable for the reinforcement and reconstruction of secondary grouting concrete structures of equipment foundations and the anchoring of anchor bolts.
Product Features
Strong and high-strength, the compressive strength can reach above 100, and the bolts can be tightened and tested within hours after grouting. The highest day intensity can reach above.
It has high self-flowing properties and can be used by adding water and stirring on site. It can fill all gaps without vibrating.
There is no shrinkage after expansion grouting, ensuring close contact between equipment bolts and foundation.
Seasonal construction allows outdoor construction to be carried out at a minimum temperature of ℃.
Durability: This product is an inorganic cementing material, and its service life is longer than the service life of the base concrete. After tens of thousands of fatigue tests
freeze-thaw cycle tests, there is no obvious change in strength.
Resistant to oil penetration and high temperature impact. After being immersed in engine oil, the strength is higher than before being immersed in oil. After planting, flame cutting and welding of the steel bars are allowed.
Scope of application
General reinforcement type
Grouting thickness << secondary grouting of equipment foundation, anchor bolt anchoring, embedded steel bars, reinforcement of building beams, plate column foundations and floors Reinforcement.
Pisolite reinforced type
Contains large aggregate, suitable for grouting layer thickness, and grouting length < secondary grouting of equipment foundation. Reinforcement and reinforcement (repair thickness) of the building's beam-slab-column foundation and floor.
Ultra-fine reinforced type

>Grouting material Grouting material Grouting material is formulated with high-strength materials as aggregates, cement as binding agent, and supplemented by high-fluid micro-expansion anti-segregation and other substances. It can be used after adding a certain amount of water at the construction site and stirring evenly. In terms of construction, it has the advantages of reliable quality, reduced cost, shortened construction period and easy use.

>Grouting material grouting construction instructions
>1 Foundation treatment
>The foundation surface should be roughened . Clean the surface of the foundation. There should be no gravel, floating ash, oil, dirt, release agent and other debris. The surface of the foundation should be fully moistened one hour before grouting, and any accumulated water should be removed one hour before grouting.
Two formwork
Set up the formwork according to the grouting construction drawing. The joints between the formwork and the basic formwork should be sealed with cement slurry tape to ensure that the entire formwork is watertight.
The horizontal distance between the formwork and the equipment base should be controlled to the left and right to facilitate grouting
construction.
The top elevation of the formwork should be higher than the upper surface of the equipment base.
If grouting occurs during grouting, it should be dealt with in time.

Preparation
Generally, add water and stir according to the standard of general_/__reinforced type
, and add water and stir according to the standard of pisolite reinforced type. Stir.
_ /__High Strength
The mixing of non-shrinkage grouting materials can be done mechanically or manually. It is recommended to use a forced mixer for mechanical mixing, which can ensure sufficient and even mixing and the mixing time is minutes. Manual mixing time is completed within minutes. The fluidity of the mixed grouting material will decrease as the parking time increases, and it should be used up within minutes. It is strictly prohibited to mix any _ /__ admixture
into the high-strength non-shrinkage grouting material.
Four grouting construction methods of grouting materials
For longer equipment or track foundations, segmented construction should be used.
After grouting begins, it must be carried out continuously without interruption, and the grouting time should be shortened as much as possible.
Five maintenance steps for high-strength non-shrink grouting material
After grouting is completed, the grouting material should be covered with a straw bag or rock wool quilt immediately after initial setting and kept moist.
During winter construction, the grouting material mixing water and maintenance measures should comply with the relevant provisions of the current "Construction Quality Acceptance Code for Concrete Structure Engineering".
