High-strength non-shrinkage grouting material
>High-strength non-shrinkage grouting material is a cement-based self-flowing micro-expanding dry mortar with early strength, high-strength self-flowing and micro-expansion properties, and is suitable for secondary grouting concrete of equipment foundations. Structural reinforcement and reconstruction, anchoring of steel bars and anchor bolts, etc.
Product Features
Early strength and high strength. The compressive strength can reach above 1 hour after grouting. The bolts can be tightened and the machine can be started for testing. 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.
No shrinkage after micro-expansive grouting to ensure close contact between equipment bolts and foundation.
In winter, outdoor construction is allowed to be carried out at a minimum temperature of ℃.
Durability: This product is an inorganic cementing material and has a service life greater than that of the base concrete. After tens of thousands of fatigue tests, there is no significant change in the strength of freeze-thaw cycles.
Oil permeation resistance and high temperature impact resistance. After being immersed in engine oil, the strength is higher than before being immersed in oil. Flame cutting and welding operations of the steel bars are allowed after the reinforcement is planted.
Scope of application

General reinforcement type
Grouting thickness << Equipment foundation Secondary grouting, anchor bolts, embedded steel bars, reinforcement and reinforcement of building beams, slabs, columns, foundations and floors.

Pisolite reinforced type
Containing large aggregates is 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
Ultra-fine aggregate is suitable for secondary grouting of equipment foundations and steel structure column footings with grouting layer thickness <<. The gaps between the concrete beams and columns reinforced angle steel and the concrete are grouted.

Super early-strength reinforcement type
The hourly strength reaches 100, which is suitable for rapid repair of cement concrete pavements such as railway sleepers, airport runways, etc., rapid repair of water sealing and leakage, and rapid repair of leaks.

>Grouting construction instructions
>One foundation treatment
>Foundation surface It should be chiseled. Clean the surface of the foundation. There should be no gravel, floating slurry, ash, oil, dirt, release agent and other debris. The surface of the foundation should be fully moistened 1 hour before grouting and any accumulated water should be removed 1 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 does not leak.
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 grout running occurs during grouting, it should be dealt with in time.
Three grouting material preparations
Generally, add water and stir according to the standards for the general reinforced type. Add water and stir according to the standards for the pisolite reinforced type.
The mixing of high-strength non-shrinkage grouting materials can be done mechanically or manually. It is recommended to use a forced mixer for mechanical mixing to ensure sufficient and even mixing for 2 minutes. Manual mixing time is completed within minutes. The fluidity of the mixed grouting material decreases as the parking time increases and should be used up within minutes. It is strictly prohibited to mix any additives into high-strength non-shrinkage grouting materials.
Four grouting construction methods
Longer equipment or track foundations should be constructed in sections.
After the grouting starts, it must be carried out continuously without interruption and the grouting time should be shortened as much as possible.
Five Maintenance
After grouting is completed, the grouting material should be immediately covered with a straw bag or rock wool quilt and kept moist after the initial setting.
The grouting material mixing water and maintenance measures during winter construction should comply with the relevant provisions of the current "Construction Quality Acceptance Code for Concrete Structure Engineering".
Do not subject to vibration for hours after grouting to avoid damaging the unhardened grouting layer.
