Product Description
Sleeve grouting material is the core component for reinforcing bar connections in prefabricated buildings. It achieves rigid connections of rebar sleeves through high-strength, non-shrinking grouting technology, thereby ensuring the structural stability of the building.
3. Application Scenarios and Features
Application scenarios Features: 1. Reinforcement connection for prefabricated structures 1. High liquidity 2. Reinforcement of shear wall structural nodes 2. Early strength and high strength 3. Waterproof connection for underground nuclear engineering 3. Micro-expansiveness 4. Grouting of tunnel segment sleeves in subway tunnels 4. Freeze-resistant and durable 5. Renovation of structural nodes in aging and outdated construction projects 5. Convenient construction 4. Technical Indicators
Inspection item Technical indicators Measured results Judgment 28-day compressive strength (MPa) ≥85.0 89.7 Qualified 28-day flexural strength (MPa) ≥10.0 10.8 Qualified Initial flowability (mm) ≥300 332 Qualified 3h Vertical Expansion Rate (%) ≥0.020 0.095 Qualified 28-day rebar bond strength (MPa) ≥30.0 36.2 Qualified 5. Functional Advantages
1. Early strength and high strength: Compressive strength reaches 35 MPa in 1 day and 65 MPa in 7 days, meeting the water requirements for rapid construction.
2. Micro-expansive property: Ensures that the sleeve makes gap-free contact with the rebar, preventing shrinkage cracks.
3. High fluidity: It can fill complex sleeve gaps without the need for vibration, boosting construction efficiency by 40%.6. Application scenarios
Suitable for various prefabricated concrete structures (shear walls, beam-column joints, precast stairs), it has been certified under the Ministry of Housing and Urban-Rural Development’s “Evaluation Standard for Prefabricated Buildings” and has been cumulatively applied to over 200 key projects nationwide.
7. Precautions for Use
Construction environment temperature: -5°C to 35°C. The water-to-cement ratio is an important performance indicator for this product. Please add water according to the manufacturer’s specified water-to-cement ratio, and use mechanical equipment to thoroughly and uniformly mix the materials before construction! If the water-to-cement ratio is improperly adjusted, it may affect the product’s performance. This product is a finished item—do not add any other substances arbitrarily, as this could damage its functionality and compromise the quality system! If this product has expired, it should be properly disposed of and no longer used. Any leftover material after mixing that has not been fully used must never be mixed with fresh material for further use! When carrying out outdoor construction in rainy weather, a rain shelter must be set up. The mixed material must be used within 30 minutes; once the initial setting time has passed, the slurry will begin to set and lose its effectiveness! Once the package is opened, the contents must be used up in one go to prevent moisture absorption and clumping.
