Product Features

💧

Ultra-high water reduction

The water reduction rate can reach 25%-40%. At the same water-cement ratio, it significantly improves concrete fluidity, enabling high-flow and self-compacting concrete.

📏

Low slump loss

Thanks to a special molecular structure design, the 1-hour slump retention rate is ≥85%, meeting the requirements of long-distance transportation and pumping construction.

⚡

High early strength

Significantly improves the 1-3 day early strength of concrete, speeds up formwork turnover, shortens the construction cycle, and improves production efficiency.

🔧

Excellent adaptability

It has good adaptability to different types of cement and supplementary cementitious materials (fly ash, slag powder, silica fume), with stable performance.

🌿

Green and environmentally friendly

It does not contain harmful substances such as formaldehyde or naphthalene-based compounds. The production process is pollution-free and meets green building material standards.

📦

Dual forms: powder and liquid

Available in both powder and liquid forms. Powder is convenient for long-distance transportation and storage; liquid is easy to use and accurately metered.

Applications

Ready-mixed concrete

Suitable for C30-C80 ready-mixed concrete of various strength grades, improving workability and strength and reducing production costs.

Precast components

Suitable for precast piles, precast beams, precast slabs, segments, and other precast components, improving early strength and accelerating mold turnover.

High-strength high-performance concrete

Suitable for C60-C150 high-strength concrete and UHPC ultra-high-performance concrete, achieving high fluidity at low water-binder ratios.

Pumped concrete

Suitable for super high-rise pumping and long-distance pumped concrete, reducing pumping pressure and the risk of pipe blockage.

Bridge and marine engineering

Suitable for bridges, ports, wharves, offshore platforms, and other projects, improving concrete durability and corrosion resistance.

Winter construction

Suitable for concrete construction in low-temperature environments, improving early strength and shortening curing time.

FAQ

What is the difference between powder and liquid water reducers? +

The active ingredients are the same; the main differences are form and method of use. Powder water reducer has a solid content of ≥95%, making it convenient for long-distance transportation and long-term storage. It needs to be dry-mixed with cement and aggregates before adding water. Liquid water reducer has a solid content of 20%-40%, is easy to use and accurately metered, and can be added directly to mixing water. It is suitable for batching plants with storage conditions.

What is the recommended dosage of the water reducer? +

The recommended dosage of powder water reducer is 0.2%-0.6% of the total cementitious material; the recommended dosage of liquid water reducer is 0.8%-2.0% (calculated by solid content). The specific dosage should be determined by testing according to concrete strength grade, cement type, construction process, and requirements. We can provide technical support.

Can the water reducer be compounded with other admixtures? +

Yes. Polycarboxylate water reducers can be compounded with retarders, early strength agents, air-entraining agents, defoamers, etc., to meet different construction requirements. However, compatibility tests are required before compounding to avoid adverse reactions. We can provide customized compounding solutions according to customer needs.

Can you provide samples? +

Yes. We provide 1-2 kg samples free of charge for customer testing. The sample freight is borne by the customer. Liquid samples can be provided in 5 kg drums.

What is the minimum order quantity? +

The minimum order quantity for regular products is 1 ton. Small trial orders are supported. Large orders (over 100 tons) can enjoy preferential prices.
