M high-strength non-shrinkage grouting material
Contact number
M 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. Features: It is suitable for secondary grouting of equipment foundations, reinforcement and transformation of concrete structures, anchoring of steel bars and anchor bolts, etc.
Product features of M high-strength non-shrinkage grouting material
. Early strength and high strength: the daily compressive strength can reach above M, and the bolts can be tightened and tested within hours after grouting. The maximum daily intensity can reach M or above.
.Has high self-flowing properties: it can be used by adding water and stirring on site, and can fill all gaps without vibrating.
.Micro expansion: no shrinkage after grouting, ensuring close contact between equipment, bolts and foundation.
.Winter construction performance: Outdoor construction is allowed at a minimum temperature of ℃.
.Durability: This product is an inorganic cementing material, and its service life is greater than that of the base concrete. After tens of thousands of fatigue tests and
freeze-thaw cycle tests, there is no obvious change in strength.
Resistance to oil penetration and high temperature impact: the strength after being immersed in engine oil is increased by more than % than before being immersed in oil. Flame cutting and welding of the steel bars are allowed after planting.

Introduction to high-strength non-shrinkage grouting material: M high-strength non-shrinkage grouting material is a cement-based self-flowing type Micro-expansion dry mortar has the characteristics of early strength, high strength, self-flow and micro-expansion. It is suitable for secondary grouting of equipment foundations, reinforcement and transformation of concrete structures, anchoring of steel bars and anchor bolts, etc.
M high-strength non-shrinkage grouting material 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 one hour before grouting. Remove any accumulated water one hour before grouting.
2. Formwork support
Set up the formwork according to the grouting construction drawing. The joints between the formwork and the foundation, and between 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 at around mm to facilitate grouting construction.
The top elevation of the formwork should be mm higher than the upper surface of the equipment base.
If grouting occurs during grouting, it should be dealt with in time.
M high-strength non-shrinkage grouting material 3. Preparation of grouting material
Generally, add water and mix according to the standard of % for the general reinforced type, and add water and mix according to the standard of % for the pisolite reinforced type.
Mechanical or manual mixing can be used to mix high-strength non-shrinkage grouting materials. 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 additives into high-strength non-shrinkage grouting materials.
M high-strength non-shrinkage grouting material 4. Grouting construction method
For long equipment or track foundation, segmented construction should be used.
After the grouting starts, it must be carried out continuously without interruption, and the grouting time should be shortened as much as possible.
M High-strength non-shrink grouting material 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" (B).
Do not subject to vibration for hours after grouting to avoid damaging the unhardened grouting layer.
Packaging, storage and transportation of M high-strength non-shrink grouting material
. Packaging specifications: / bag, stored in a ventilated and dry place and protected from direct sunlight.
.The shelf life is one month. If it exceeds the shelf life, it should be re-inspected before it can be used.
