Sleeve Grout Technical Support Self-Leveling Self-Leveling Grouting Material for Cold Region Project

Sleeve grout is a special high-strength material dedicated to steel bar sleeve connection for prefabricated buildings, complying strictly with JG/T 408 industry standards. It features C85-C100 ultra-high strength, high flow retention and dual micro-expansion, specially designed for narrow gap filling and steel bar anchoring. Ordinary grout has lower strength, unqualified fluidity and expansion performance, which cannot meet the strict standards of equal-strength connection, seismic resistance an

It is specially used for vertical and horizontal steel bar sleeve grouting connection of prefabricated concrete buildings, widely applied to prefabricated shear walls, frame columns, beam-column joints, high-rise prefabricated residences and industrial prefabricated workshops. It is the core special building material for component splicing, steel bar anchoring and joint reinforcement of prefabricated construction projects.

The construction base must be clean, solid, dust-free, oil-free and free of loose debris, and the inside of the sleeve must be unobstructed. Construction shall avoid extreme high and low temperatures. Mix strictly according to the standard water-binder ratio without random water addition. Professional grouting equipment is required to ensure stable fluidity and dense filling, avoiding voids and material shortage defects.

No such problems will occur with standard construction. Adopting dual micro-expansion formula, it compensates shrinkage throughout the whole process without settlement or segregation. The self-flowing slurry fills gaps completely. After hardening, it forms an integrated dense structure with steel bars and sleeves, featuring excellent deformation and crack resistance. No voiding, loosening or cracking occurs in long-term service to ensure structural safety of prefabricated joints.

With chloride-free eco-friendly formula, it contains no corrosive ingredients and will not rust steel bars and metal sleeves. The hardened dense structure has excellent impermeability, frost resistance, aging resistance and chemical corrosion resistance. It isolates air and moisture to resist external erosion, ensuring long-term stability and safety of prefabricated building connection joints.
