CGM non-shrinkage grouting material

Non-shrinkage grouting material
Implementation standard "Cement-based grouting material"
Product introduction
High-strength non-shrinkage grouting material uses high-strength materials as aggregates and cement as binding agent. It is formulated with high fluidity, micro-expansion, anti-segregation and other substances. Add a certain amount of water at the construction site and mix evenly before use.
Product Features
◎High-strength pouring early and the strength the day after is as high as possible, shortening the construction period.
◎The crack resistance and water resistance can reach the impermeability mark.
◎In the self-flowing state, you only need to add water and stir on site, and then pour it directly into the equipment foundation. The mortar flows by itself and the construction is vibration-free, ensuring vibration-free and long-distance grouting construction.
◎The micro-expansion castable body will not shrink after long-term use, ensuring close contact between the equipment and the foundation.
◎Oil permeation resistance: After being immersed in engine oil for several days, its strength is improved. It is molded, dense, impermeable, and adaptable to the oily environment of the machine base.
◎Durability after 10,000 times fatigue test, there is no significant change in strength in freeze-thaw environment test.
Scope of application
Anchor bolt anchoring, emergency repair of airstrips, fixation of nuclear power equipment, reinforcement of road and bridge projects, machine bases, steel structures and foundation pockets, secondary grouting of equipment foundations, and buried steel bars , Reinforcement and renovation of concrete structures, crack management of old concrete structures, installation of mechanical and electrical equipment, installation of tracks and steel structures, pile sealing in static pile pressing projects, thickening of wall structures and repair of water leakage, various foundation projects Collapse grouting and various emergency repair projects, etc.

Construction steps
Prepare mixing machines, grouting equipment, formwork and maintenance items, clean the grouting space and wet the concrete surface in advance.
, Set up the formwork and seal the joints of the formwork with cement (sand) slurry and plastic tape to ensure no water or slurry leakage.
, Add water according to the weight of the grouting material and stir (mechanical stirring for 10 minutes, manual stirring for more than 10 minutes)
, Pour the evenly stirred grouting material into the grouting part from one direction. If necessary, bamboo strips or steel drills can be used to guide the flow, and the template can be properly vibrated or lightly tapped.
After the construction is completed, it should be covered immediately with plastic film and covered with straw curtains or quilts for a moist and humid curing day.
, The use temperature is ℃ to ℃. It is strictly prohibited to mix any additives or external additives into the grouting material.
