Product features
Early strength and high strength
Day compressive strength Day compression Strength is the compressive strength.
Micro expansion
Ensures close contact between the equipment and the foundation, and no shrinkage after secondary grouting.
High self-flowing properties
Can fill all gaps and meet the requirements of secondary grouting of equipment.
Strong durability
After millions of fatigue tests and freeze-thaw cycles, the strength does not change significantly. The strength is significantly improved after soaking in engine oil.
Winter construction is possible
Outdoor construction is allowed at temperatures of ℃.
Product Usage

Grouting construction
The first step is foundation treatment
The foundation surface should be roughened, or a special reinforcing interface agent concrete interface agent should be used for interface treatment.
Clean the surface of the foundation, and there should be no gravel, laitance, ash, oil, dirt, release agent and other debris.
Before grouting, the foundation surface should be fully moistened, and any accumulated water should be removed before grouting.
The second step is to set up the 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 sealing agent, tape, etc. 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.
The third step is to prepare the grouting material
Generally, add water and stir according to the standard for the general reinforced type, and add water and stir according to the standard for the pisolite reinforced type.
It is recommended to use mechanical mixing method. The mixing time is generally strictly prohibited and it is strictly forbidden to use a hand drill-type mixer. When using manual mixing, you should first add /% of water to mix, then add the remaining amount of water and mix until uniform.
The amount of stirring each time should be determined according to the usage amount to ensure that the material is used up within the time limit.
When used on site, it is strictly prohibited to mix any additives into the grouting material.
The fourth step of grouting construction method
For longer equipment or track foundations, segmented construction should be used.
Illustrations of several commonly used grouting methods
During secondary grouting, the following requirements should be met.
① During secondary grouting, grouting should be carried out from multiple points on one side or adjacent two sides until it overflows from the other side to facilitate exhaust during the grouting process. Grouting shall not be carried out from all four sides at the same time.
②After grouting begins, it must be carried out continuously without interruption. And shorten the grouting time as much as possible.
③Vibration is strictly prohibited during the grouting process. If necessary, the grouting booster can be used to push the grouting material along the bottom of the grouting layer. It is strictly prohibited to push from the middle of the grouting layer to ensure the homogeneity of the grouting layer.
④After the equipment foundation grouting is completed, a bevel should be cut outward along the edge of the equipment after grouting to prevent cracks at the free end. If edge trimming cannot be performed, the surface of the grouting layer should be trimmed with a spatula after grouting. Calendered.
⑤ When the thickness of the grouting layer exceeds the thickness of the grouting layer, pisolite-reinforced high-strength non-shrinkage grouting material should be used.
⑥When the equipment foundation grouting volume is large, mechanical stirring should be used to stir the pisolite-reinforced grouting material to ensure grouting construction.
The fifth step of maintenance
After grouting is completed, the interior should be covered with wet grass or rock wool quilt immediately and kept moist.
During winter construction, maintenance measures should also comply with the relevant provisions of the current construction and acceptance specifications for reinforced concrete projects.
After the grouting material reaches the film removal time, the equipment can be installed. For the specific time, please refer to the relationship table between film removal and curing time and ambient temperature.

Maintenance time []
After the equipment foundation grouting is completed, if there is any part that needs to be removed, it can be removed after the grouting is completed. , that is, gently remove the grout layer with a spatula or shovel before it hardens.
The vibration of the running machine must not be transmitted to the equipment foundation. The machine should be stopped after the second grouting to avoid damaging the unhardened grouting layer.
Packaging, Storage and Transportation
