Product features, early strength, high strength: Tiankang Compressive strength&, compressive strength&, compressive strength&. , Micro expansion: ensure close contact between equipment and foundation, no shrinkage after secondary grouting. . High self-flowing property: can fill all gaps and meet the requirements of secondary grouting of equipment. . Anti-segregation: Overcome the segregation phenomenon caused by adding too much water during on-site use. , Anti-cracking: Cracks may occur during on-site use due to factors such as uncertainty in the amount of water added, uncertainty in ambient temperature, and limitations in maintenance conditions. . Strong durability: After millions of fatigue tests and freeze-thaw cycles, the strength has no significant change. The strength is significantly improved after soaking in engine oil. , Can be constructed in winter: outdoor construction is allowed at -℃ temperature.
Product usage
Used for secondary grouting of equipment foundation.
, used for anchoring anchor bolts and burying steel bars.
, used for reinforcement and repair of concrete structures.
, used for grouting reinforcement of steel frame supports.
/High-strength bearing grouting material
High-strength bearing grouting material is an upgraded and improved second-generation inorganic, high-strength, early-strength, micro-expansion grouting material based on years of application practice of grouting materials.
Product Features
. Early strength and high strength: the compressive strength can reach - or above in 1 day.
. High self-flowing property: it can fill all the gaps and meet the requirements of secondary grouting of the equipment.
.Micro expansion: ensure close contact between the equipment and the foundation, and no shrinkage after secondary grouting. The bonding strength is high, and the holding force with steel bars is not less than that.
. Can be constructed in winter: outdoor construction is allowed at -℃ temperature.
. Strong durability: This product is an inorganic cementing material, and its service life is greater than the service life of the base concrete. After millions of fatigue tests, there is no significant change in the strength of the freeze-thaw cycle test. The strength is significantly improved after soaking in engine oil.
Product usage
. Suitable for secondary grouting of machine bases, anchor bolts and other equipment as well as steel structures (rails, steel frames, steel columns, etc.) fixedly connected to the foundation.
. Reinforcement, repair and reinforcement of building beams, slabs, columns, foundations, floors and roads.
. Can be used for anchoring anchor bolts and steel bars and structural reinforcement.

Construction steps
. Prepare mixing equipment, 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 -% of the weight of the grouting material with water and stir (mechanical stirring for - minutes, manual stirring for more than 1 minute).
. 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, the curing agent should be sprayed immediately or covered with plastic film and covered with straw curtains or quilts for one day of moist curing.
. The operating temperature is -℃ to ℃. It is strictly prohibited to mix any additives or external additives into the grouting material.
Packaging, storage and transportation
. The bearing grouting material is packed in bags and stored in a ventilated and dry place away 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. Wear-resistant materials, ultra-high-strength road repair mortar, epoxy repair mortar, track mortar, steel anchor materials, primary seat slurry, bearing mortar, cement self-leveling mortar, grouting resin, concrete recasting agent interface agent, dry powder interface agent , R joint repair mortar, reinforcement glue, flexible cement caulking material, polymer waterproof mortar, steel bar embroidery resistance agent, construction glue (concentrated powder), steel glue, carbon cloth glue, tile adhesive, waterproof coating, putty Powder and other site construction materials are sold directly by manufacturers at preferential prices
