15101060180 Song manager grouting material manufacturer, grouting price, grouting standard, grouting direct sales, Beijing grouting material manufacturer, grouting material, the country's largest production and sales product features 1, early strength, high strength: 1 day compressive strength ≥ 20Mpa, 3 days anti- The compressive strength is ≥30Mpa, and the 28-day compressive strength is ≥55Mpa. 2, micro-expansion: to ensure close contact between the equipment and the foundation, no shrinkage after secondary grouting. 3, high self-flow: can fill all the gaps, to meet the requirements of equipment secondary grouting. 4, anti-segregation: Overcome the segregation phenomenon caused by the excessive amount of water in the field use. 5. Anti-cracking: Cracks in the field due to uncertain water addition, uncertain ambient temperature and limitations of curing conditions. 6. Durable: There is no significant change in the strength of the 50 freeze-thaw cycles tested by Beijing grouting mills. The strength was significantly improved after soaking for 30 days in the oil. 7. Winter construction: Allow outdoor construction at -10 °C.
Product Usage
1. Used for secondary grouting of equipment foundation.
2. Used for anchoring anchor bolts and reinforced steel.
3. Used for reinforcement and repair of concrete structures.
Beijing/CGM high-strength non-shrinkage grouting material Beijing Gaoqiang non-shrinkage grouting material is a second-generation inorganic, high-strength, early-strength and micro-expansion grouting material upgraded and improved on the basis of many years of application practice of CGM grouting material manufacturers.
Features
1. Early strength, high strength: 1-3 days compressive strength can reach 30-50Mpa or more.
2. High self-flow: it can fill all the gaps and meet the requirements of secondary grouting of equipment.
3. Micro-expansion: ensure close contact between the equipment and the foundation, no shrinkage after secondary grouting. The bonding strength is high, and the reinforcing force of the steel bar is not less than 6Mpa.
4. Winter construction: outdoor construction is allowed at -10 °C.
5. Durable: This product is an inorganic cement material with a service life greater than the service life of the foundation concrete. After millions of fatigue tests, there was no significant change in the intensity of the 50 freeze-thaw cycles. The strength was significantly improved after soaking for 30 days in the oil.
Product Usage
1. It is suitable for secondary grouting of machine base, anchor bolts and other equipment as well as steel structure (rail, steel frame, steel column, etc.) and foundation fixed connection.
2. Reinforcement, repair, and reinforcement of beams, slabs, columns, foundations, floors, and roads of buildings.
3. Anchoring and structural reinforcement of anchor bolts and steel bars.

Construction steps
1. Prepare mixing equipment, grouting equipment, formwork and maintenance items, clean the grouting space and wet the concrete surface in advance.
2. Support the template and seal the joint of the template with cement (sand) pulp and plastic tape to ensure no water leakage or slurry leakage.
3. Add 12-15% of the grout weight to the water and stir it (mechanically stirred for 2-3 minutes, manually stirred for 5 minutes or more).
4. Fill the grout with a well-mixed grout from one direction. If necessary, it can be guided by bamboo strips or steel brazing, and the template can be appropriately vibrated or tapped.
5. Immediately after the completion of the construction, spray the curing agent or cover the plastic film and cover with straw curtain or quilt for 3-7 days.
6. The operating temperature is -10 ° C to 40 ° C. It is strictly forbidden to incorporate any admixture or external admixture into the grout.
Packaging and transportation
1. The grout is packed in 50kg bags, stored in a dry and ventilated place and protected from direct sunlight.
2. The warranty period is 3 months, and the warranty period should be re-examined.
