HGM/CGM high strength non-shrinkage grouting material

Product Introduction
High-strength non-shrinkage grouting material is formulated with special water. This product has early strength, high strength, no shrinkage, micro-expansion, large fluidity, self-flow and vibration-free, non-toxic, harmless, non-aging, and non-toxic. There is no pollution in the water quality and surrounding environment, and it has the characteristics of good self-tightness and rust prevention.
Fundamentally change the stress situation of the equipment base so that it can evenly bear the entire load of the equipment, thereby meeting the installation requirements of various machinery, heavy equipment, and high-precision grinders. It is an ideal grouting material in the era of backing-free installation. .
Scope of application
Anchor bolt anchoring, steel structure and foundation interface reinforcement, machine base reinforcement, secondary grouting of equipment foundation, mechanical and electrical equipment installation, static piling engineering pile sealing, concrete structure reinforcement and transformation , Crack control of old concrete structures, thickening of wall structures and repair of water leakage, reinforcement of road and bridge projects, collapse grouting of various foundation projects, and various emergency repair projects, etc.

Packaging
Moisture-proof packaging
Storage
It can be stored for
months if the dry sealed bag is in good condition. If it exceeds
months, it can only be used after testing.
Durability
Fatigue test
, Freeze-thaw cycle test strength has no significant change.
Implementation standards
/
"Cement-based grouting material standards"
/
"Cement-based grouting material application technical specifications".
Foundation Treatment
Clean the surface of the foundation and there should be no gravel, laitance, dust, oil, release agent and other debris.
Before grouting
The foundation surface should be fully moist. Before grouting
Standing water should be absorbed.
Formwork support
Set up the formwork according to the determined grouting method and grouting construction drawing. The formwork must be supported tightly and firmly to prevent loosening and grout leakage. When setting up the formwork for the equipment foundation,
the positioning elevation of the formwork should be at least
higher than the upper surface of the equipment base, and the horizontal distance between the formwork and the equipment base should be controlled
to facilitate grouting construction.
Stirring of grouting material
The amount of water added according to the standard consistency is

The water used for mixing should be tap water,
The water temperature should be
℃
, mechanical or manual mixing can be used. When mechanical stirring is used, the stirring time is generally minutes. When manual stirring is used,
it is advisable to first add the
/
amount of water and stir for
minutes, then add the remaining amount of water and continue stirring until uniform.
When the equipment foundation grouting volume is large, mechanical stirring should be used to ensure grouting construction.
Grouting
The grout should be poured from one side until it overflows from the other side, so as to facilitate the discharge of air between the equipment base and the concrete foundation and enrich the grouting. Vibration is strictly prohibited during the grouting process. If necessary, bamboo slats, etc. can be used for pulling and diversion.
If grout running occurs during grouting,
it should be dealt with promptly. Grouting for longer equipment or track foundations should be carried out in sections. The length of each section should be
.
If there is bleeding on the surface during the grouting process, sprinkle a small amount of dry material on the material to absorb the water.
Maintenance
After removing the formwork, the grouting layer should be watered and cured immediately. The curing temperature should be >
℃
, and the curing period should be >
days. It is best to use spraying. Conservation agent measures. During winter construction, maintenance measures should also comply with the relevant provisions of the current "Construction Acceptance Code for Reinforced Concrete Projects"
