High-strength non-shrinkage grouting material
High-strength non-shrinkage grouting material is a cement-based self-flowing micro-expansion dry mortar with early strength, high strength, self-flow and micro-expansion. With other characteristics, it is suitable for secondary grouting of equipment foundations, reinforcement and transformation of concrete structures, anchoring of steel bars and anchor bolts, etc.
Grouting material product features
Strong, high-strength compressive strength can reach above 100%. 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 and
freeze-thaw cycle tests, there is no obvious change in strength.
, oil seepage resistance, high temperature impact resistance, the strength after immersion in engine oil is higher than before oil immersion, flame cutting and welding operations of steel bars are allowed after planting.
Applicable scope of grouting material


Universal type

Grouting thickness << secondary grouting of equipment foundation, anchor bolt anchoring, buried steel bars, construction Reinforcement of beams, slabs, columns, foundations and floors.



Pisolite type

Contains ~ large aggregate, suitable for grouting layer thickness, and grouting length < secondary grouting of equipment foundation. Reinforcement (repair thickness) of building beams, slabs, columns, foundations and floors.



Ultra-fine type

Ultra-fine aggregate, 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.



Early strength type

The hourly strength is reached, and it is suitable for rapid repairs such as railway sleepers, cement concrete pavements, airport runways, etc. Quick repair of water stop and leakage.

Grouting construction instructions
1. Foundation treatment
The surface of the foundation should be roughened. Clean the foundation surface. There should be no gravel, floating slurry, floating ash, oil stains, release agents and other debris. The foundation surface should be fully moistened 1 hour before grouting. Remove accumulated water 1 hour before grouting.
Two, support the formwork
Set up the formwork according to the grouting construction drawing. The joints between the formwork and the foundation, as well as the formwork and the formwork, are sealed with cement slurry, tape, etc. to ensure that the entire formwork is watertight.
, The horizontal distance between the formwork and the base of the equipment 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.
3. Preparation of grouting material
Generally, add water and stir according to the standard for general reinforced type, and add water and stir according to the standard for 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, 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 should be used up within minutes. It is strictly prohibited to mix any additives into high-strength non-shrinkage grouting materials.
Four. Grouting construction method
For longer equipment or track foundations, segmented construction should be used.
After grouting starts, it must be carried out continuously without interruption, and the grouting time should be shortened as much as possible.
5. Maintenance
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, grouting materials, mixing water and maintenance measures 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.
