Key Features
- High Water Reduction (≥30%) — Achieves a water-reduction rate of 30% or higher, effectively lowering the water-to-binder ratio to enhance density, compressive strength, and overall durability.
- Rapid Solubility — Dissolves quickly and completely in cold water with no caking or residue, ensuring convenient handling and consistent dosing.
- Superior Storage Stability — As a dry powder, it offers an extended shelf life with no sedimentation or stratification, making it ideal for long-distance transport and long-term storage.
- Excellent Early Strength — Accelerates early strength development, shortening curing time and speeding up formwork turnover to improve construction efficiency.
- Broad Compatibility — Performs reliably with all types of cement, chemical admixtures, and dry-mortar additives, ensuring stable formulation across diverse systems.
- Versatile Application — Suitable for both dry-mortar compounding and on-site dissolution for ready-mix concrete, offering flexible use across multiple scenarios.
Applications
- Dry mortar, special mortar products
- Non-shrink grout, duct grouting material
- Powder concrete admixture compounding
- Precast concrete elements
- Long-distance transportation and export scenarios
- Special engineering dry powder products
Recommended Dosage
- Normal dosage is 0.2%-0.5% of total cementitious materials weight, optimal dosage determined through trial mixing
- In dry mortar, it can be directly mixed evenly with other powders; for on-site use, it can be dissolved in mixing water first
Packaging
- 25kg laminated woven bag/kraft paper bag with PE moisture-proof liner
- 1000kg bulk bag
- Customized packaging available according to customer requirements
Storage & Transportation
- Store in dry, ventilated warehouse, moisture-proof, rain-proof, avoid direct sunlight
- Shelf life 12 months under original sealed packaging, use as soon as possible after opening
- Transport as non-dangerous goods, prevent package damage and moisture during transportation
