High-strength non-shrinkage grouting material
Product features
, early strength, high strength
Day compressive strength Day compressive strength Day compression strength-.
, micro-expansion
Ensure close contact between equipment and foundation without shrinkage after secondary grouting.
, high self-flowing property
Can fill all the gaps to meet the requirements of secondary grouting of the equipment.
, strong durability
After millions of fatigue tests and freeze-thaw cycles, there is no significant change in strength. The strength is significantly improved after soaking in engine oil
and can be constructed in winter
Outdoor construction is allowed at -℃ temperature.

, straw bags, rock wool quilts, etc. , cotton yarn, tape.
Grouting construction
The first step: foundation treatment
The surface of the foundation should be roughened or a special reinforcing interface agent-concrete recasting agent should be used for interface treatment.
There should be no debris, floating slurry, floating ash, oil stains, release agents and other debris on the surface of the clean foundation.
Before grouting, the foundation surface should be fully moistened and any accumulated water should be removed before grouting.
Step 2: Set up the formwork
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 should be sealed with cement slurry (quick leak-stopping agent recommended), 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 template should be higher than the upper surface of the equipment base.
If grouting occurs during grouting, it should be dealt with in time.
Step 3: Preparation of grouting material
Generally, add water and stir according to the standard of -% for the general reinforced type. Add water and stir according to the standard of -% for the pisolite reinforced type.
It is recommended to use mechanical mixing method and the mixing time is generally - (hand-operated electric drill mixers are strictly prohibited). When using manual stirring, add / of the amount of water to mix first, then add the remaining amount of water and mix until uniform.
The amount of mixing each time should be determined according to the usage amount to ensure that the materials are used up within the time limit.
. It is strictly prohibited to mix any additives or external additives into the grouting material when used on site.
Step 4: Grouting construction method
For longer equipment or track foundations, segmented construction should be used.
. Illustrations of several commonly used grouting methods:
. The following requirements should be met during secondary grouting.
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.
② After the grouting starts, it must be carried out continuously without interruption. And shorten the grouting time as much as possible.
③ Vibration is strictly prohibited during the grouting process. If necessary, a grouting booster can be used to push the grouting material along the bottom of the grouting layer. It is strictly forbidden to push from the middle or upper part of the grouting layer to ensure the homogeneity of the grouting layer.
④. After the equipment foundation grouting is completed, a bevel should be cut outward along the edge of the equipment 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, reinforced high-strength non-shrinkage grouting material should be used.
⑥. When the equipment foundation grouting volume is large, mechanical stirring should be used to stir the reinforced grouting material to ensure grouting construction.
Step 5: Maintenance
After grouting is completed, the interior should be covered with wet grass or rock wool quilt immediately and kept moist.
. Maintenance measures during winter construction should also comply with the relevant regulations of the current reinforced concrete engineering construction and acceptance specifications ()
.
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
If there is any part that needs to be removed after the equipment foundation grouting is completed, it can be gently removed with a spatula or shovel tool after the grouting is completed and before the grouting layer 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 and storage:
The standard packaging specification is kg/bag. It should be stored in a dry and ventilated environment, waterproof and moisture-proof. The shelf life is one month in an unopened state and can be transported as general cargo.
