CHENGLI Early Strength Polycarboxylate Superplasticizer Liquid (Model CL-SR-50) | Concrete Admixture

Key Features & Benefits:

• High Water Reduction: Achieves a high water-reducing rate, typically over 25% and up to 45%, which leads to denser concrete and higher compressive strength .
• Early Strength Development: Promotes rapid strength gain at early ages (1-day and 3-day), making it ideal for precast concrete production and projects with fast construction schedules .
• Excellent Slump Retention: Maintains the fluidity and workability of the concrete mix for an extended period, facilitating pumping and placement over longer distances and timeframes .
• Low Chloride & Low Alkali: Contains minimal chloride ions and low alkali content, preventing corrosion of steel reinforcement and enhancing the long-term durability of concrete structures .
• Environmental Safety: Formulated to be non-toxic, non-flammable, and environmentally safe, meeting international environmental standards .

Recommended Dosage:

The standard dosage range is typically 0.4% to 2.0% of the total weight of cementitious materials (cement, fly ash, slag, etc.). The most common recommended dosage is around 1.0% . However, the optimal dosage should be determined through concrete trial mixes based on the specific raw materials and project requirements.

Application Guidelines:

• Mixing: Add the liquid superplasticizer to the mixing water or directly into the concrete mixer during the batching process. Ensure uniform mixing for at least 60-90 seconds.
• Compatibility: While it has good compatibility with most cements, it is recommended to conduct compatibility tests with local cement and other admixtures (if used simultaneously) to avoid any adverse effects .
• Water Control: Strictly control the amount of mixing water, as the slump is highly sensitive to water content .
• Curing: Standard concrete curing practices must be followed to ensure optimal strength development and surface quality.

Typical Applications:

• High-strength and high-performance concrete (C50 and above)
• Precast and prefabricated concrete elements
• Self-compacting concrete (SCC)
• Pumped concrete for high-rise buildings and long-distance transportation
• Bridge decks, pavements, and other infrastructure requiring high durability
• Concrete projects in hot weather conditions where slump retention is critical

Price & Packaging:

Prices are typically quoted per metric ton (MT) and vary based on order quantity. Common packaging includes 25kg bags, 200kg drums, or 1000kg IBC totes. Special packaging options are available upon request .

• Price Range: The market price for polycarboxylate superplasticizer liquid can range from approximately $200 to $1,800 per ton, depending on the concentration, quality, and order volume .
• Minimum Order Quantity (MOQ): The standard MOQ is often 1 ton, but some suppliers may offer smaller quantities for sample testing or initial orders .
