This product is chlorine-free and low in alkali, non-toxic and non-corrosive. It is suitable for ready-mixed concrete, pumping, high and low temperature early-strength concrete. It has excellent slump retention properties, adjustable setting time, and can reduce water consumption while saving cement.
Ⅰ. Product Standards
Complies with JC 473-2001 "Pumping Agents for Concrete" standard. This series includes:
Model YS-BI-100: Standard Type
Model YS-BI-200: Early-Strength Type


Ⅱ. Application Scope
1. Versatility: Suitable for commercial ready-mixed concrete, concrete with early-strength or retarding requirements, site-mixed concrete, and pumped concrete.
2. Environment: Ideal for construction in hot summer or high-temperature environments, and projects requiring low slump loss.
3. Low Temperature: Model YS-BI-200 (Early-Strength) is suitable for construction at minimum temperatures not lower than -5°C where early-strength development is required.
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. Air Entrainment: Excellent air-entraining performance with air content ≤ 5.5%.
3. Pumpability & Workability:
Flowability: Strong dispersion effect on cement, increasing concrete slump by 8cm–10cm with minimal loss.
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.
4. Low Alkali: Na_2SO_4 \le 18\%. Low alkali content prevents Alkali-Aggregate Reaction (AAR).
5. Efficiency:
Water Reduction Rate: 10%–18%, significantly improving strength at all ages.
Cement Saving: Saves 7%–20% of cement while maintaining constant strength.
6. Durability: Enhances impermeability, freeze-thaw resistance, and carbonation resistance. Reduces shrinkage and creep, effectively extending the service life of the concrete.
Ⅳ. Recommended Dosage
Powder: 0.8% – 4.0% of the total weight of cementitious materials.
Liquid: 1.3% – 4.0% 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:
Powder: Add to the mixer together with the binder. Extending the mixing time slightly is recommended for optimal dispersion.
Liquid: Typically added with the mixing water. For enhanced effects, add later in the mixing process or just before pouring (with thorough stirring).
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.
