- Excellent dispersibility and fluidity for cement even at low dosages;
- Significant increase in paste fluidity when dosage ranges from 0.12% to 0.22%;
- No fluidity loss of paste after 1 hour;
- Fluidity is more than twice that of commercially available high-efficiency water reducers.
3. Mortar Performance
- Mortar water reduction rate corresponds to paste fluidity: higher paste fluidity leads to higher mortar water reduction rate;
- Water reduction rate increases rapidly with dosage and remains at a high level; at the same dosage, it is approximately 35% higher than that of commercially available high-efficiency water reducers;
- Concrete water reduction rate may differ from mortar water reduction rate due to the influence of admixtures and aggregate properties: if admixtures and aggregates enhance concrete fluidity, concrete water reduction rate will exceed that of mortar; otherwise, it will be lower;
- Antifreeze performance at temperatures above -5℃, suitable for use as an antifreeze agent in concrete.

Concrete mixed with powder water reducer has lower bleeding rate and shrinkage rate than the reference concrete; initial setting time is extended by approximately 60 minutes compared to the reference, while final setting time is nearly the same; air content is generally controlled at 2–4%.
Recommended Dosage
Recommended dosage for concrete: 0.1~0.25% of cement dosage. The water reducer is a powder with polycarboxylate as the main component (solid content ~98%). The normal dosage is 0.12%–0.3%:
- At a dosage of only 0.06%, it achieves a 12% water reduction rate and 23% strength growth, outperforming commercially available ordinary pumping agents;
- At 0.1% dosage, its performance exceeds that of general naphthalene-based and melamine-based high-efficiency water reducers;
- Below 0.14% dosage, the superiority in workability is not significant;
- Above 0.20% dosage, concrete workability and pumpability reach an excellent level.
Optimal recommended dosage: 0.12–0.24%. For high-strength concrete, concrete with high-volume fly ash/slag powder, or concrete with special requirements, dosage can be increased to over 0.3% (but generally not exceeding 0.5%). Tests show that at 0.5% dosage, concrete does not experience cohesion loss or aggregate-paste segregation, water reduction rate continues to rise, but air content increases, setting is delayed, and strength decreases slightly.
Polycarboxylate-based high-performance water reducers represent a new generation of high-performance water reducers that have emerged domestically and internationally in recent years. Compared with traditional high-efficiency water reducers such as naphthalene-based ones, polycarboxylate-based high-performance water reducers boast numerous unique technical performance advantages:
- (1) Low dosage and high water reduction rate;
- (2) Excellent retention of fluidity for concrete mixtures;
- (3) Good compatibility with cement;
- (4) The concrete prepared with them exhibits low shrinkage, which helps improve the volume stability and durability of concrete;
- (5) They are environmentally friendly and pollution-free during production and use, falling into the category of green admixtures.

Frequently Asked Questions
What are the apparent properties of this Polycarboxylate Superplasticizer Polyether?
It has a density of 500±15, solid content of 98±1%, pH value of 6–7, chloride ion content of less than 0.1%, and total alkali content of less than 5%.
What is the optimal recommended dosage of the powder water reducer?
The optimal recommended dosage is 0.12–0.24% of the cement dosage. For high-strength concrete or special requirements, the dosage can be increased up to 0.3%–0.5% after testing.
How does the water reducer perform at low temperatures?
It provides excellent antifreeze performance at temperatures above -5℃, which makes it highly suitable as an antifreeze admixture in concrete projects.
How does this product affect the setting time and air content of concrete?
The initial setting time is extended by approximately 40 to 80 minutes, while the final setting time is only slightly extended (0 to 10 minutes). The air content is generally controlled within 2% to 4%.
What certifications verify the quality of your supply chain and chemicals?
The processes are triple-certified under REACH, ISO 9001, and FMQS standards. These ensure full compliance with global safety, hygiene, and chemical quality regulations.
