Suitable for preparing high-strength or ultra-high-strength concrete, self-compacting concrete, concrete with high requirements for density and durability, as well as concrete for ultra-high pumping or long-distance pumping.
Ⅰ. Product Standards
Complies with JC 473-2001 "Pumping Agents for Concrete" standard. The series includes:
Model YS-B-100: Standard Type
Model YS-B-200: Early-Strength Type
Ⅱ. Application Scope
1. Specialized Concrete: Ideal for high-strength or ultra-high-strength concrete, self-compacting concrete (SCC), and concrete with high density and durability requirements.
2. Challenging Pumping: Designed for ultra-high-altitude pumping or ultra-long-distance pumping projects.
3. Mineral Admixtures: Suitable for concrete with high or ultra-high dosages of mineral admixtures (e.g., fly ash, slag).
4. High Requirements: Suitable for high-performance concrete (HPC) requiring excellent workability or superior early strength.
5. Low Temperature: Applicable for various concrete projects under construction temperatures not lower than -5°C with early-strength requirements.
Ⅲ. Performance Characteristics & Technical Specifications
1. Safety: Non-toxic, non-flammable, and non-corrosive with a stable morphology. Chlorine-free to ensure no corrosion to reinforcement bars.
2. Low Alkali: Na_2SO_4 < 3\%. Extremely low alkali content effectively prevents Alkali-Aggregate Reaction (AAR).
3. Air Entrainment: Moderate air-entraining performance with air content ≤ 3%.
4. Pumping & Workability:
Flowability: Strong dispersion effect on cement, increasing slump by 10cm–15cm with minimal loss over time.
Pumping Performance: Pressure Bleeding Rate Ratio < 90%, ensuring the mixture is easy to pour, vibrate, and pump.
Adjustability: Setting time is highly adjustable based on project needs.
5. Efficiency & Strength:
Water Reduction: \ge 20\%.
Strength Increase: Significantly enhances strength at all ages; 3d–7d strength increases by 25%–45%; 28d strength increases by 20%–40%.
Cement Saving: Saves over 20% of cement while maintaining constant strength.
Durability: Significantly improves impermeability, freeze-thaw resistance, and carbonation resistance, effectively extending the service life of the concrete.
Ⅳ. Recommended Dosage
Powder: 2.0% – 4.5% of the total weight of cementitious materials.
Liquid: 1.5% – 4.5% of the total weight of cementitious materials.
Ⅴ. Instructions for Use
Testing: Compatibility and dosage should be determined via trial mixes according to specific project materials, mix designs, and requirements.
Addition Method:
Liquid: Typically added with the mixing water. For enhanced effects, add later in the mixing process or just before pouring (with thorough stirring).
Powder: Add to the mixer together with the binder. Extending the mixing time slightly is recommended for optimal performance.
Ⅵ. Packaging, Transportation & Storage
Packaging:
Powder: Double-layer packaging (inner plastic liner, outer woven bag), 25kg or 40kg net weight per bag.
Liquid: Available in drums or tanks.
Logistics: Protect powder from bag breakage and moisture during transit. Ensure liquid containers are sealed to prevent leakage.
Storage:
Powder: Store in a ventilated, dry, dedicated warehouse. Protect against clumping due to moisture. If clumping occurs, use only after passing a 0.63mm sieve test to re-determine dosage.
Liquid: Store in a cool, dry place; avoid prolonged exposure to direct sunlight.
Shelf Life: One year. The product may still be used after the expiration date if it passes re-testing.
