Liquor Water Reducer

• Polycarboxylate Superplasticizer is a type of water-reducing admixture based on polycarboxylate ether polymers.
• Its design is intended to effectively disperse cement particles, maintaining or enhancing concrete workability while significantly reducing water consumption.
• Offers high efficiency compared to earlier generations like naphthalene sulfonates or lignosulfonates.

Composition and Chemistry

• Main components:
  • Polycarboxylate ether backbone (polymer chains).
  • Pendant side chains (usually polyethylene glycol or similar) that provide steric hindrance.
• The chemical structure allows for strong adsorption on cement particles, providing excellent dispersing action.

Benefits of Polycarboxylate Superplasticizers

• High fluidity at low dosages: Enhanced flowability with less superplasticizer.
• Reduced water-cement ratio: Improves strength and durability.
• Excellent slump retention: Maintains workability over time.
• Compatibility: Suitable for various types of cement and supplementary cementitious materials.

Packaging and storage

1. The product is transported in plastic barrels or tank trucks and can also be packed in particular ways according to customer requirements;
2. The product is non-toxic and non-flammable;
3. Store the product in a cool place. Avoid long-term contact with steel products, cover for storage, avoid the sun, rain, and freezing, and the storage temperature should be between 0-40 ℃, lower than 0 ℃. There will be a phenomenon of freezing during storage. If it froze, heat until it melts and stir again before use;
4. The shelf life is six months. If it exceeds, it can continue to be used after the technical indicators have passed the inspection and the performance indicators have been confirmed to meet the requirements by concrete trial mix verification.

Polycarboxylic superplasticizer, as a new generation of water-reducing products, owns numerous significant advantages over traditional high-performance water reducers such as naphthalene sulfonate formaldehyde condensate (SNF) and sulfonated melamine formaldehyde resin (SMF). It exhibits higher water reduction rates, achieving outstanding performance at lower dosage levels. Additionally, polycarboxylic superplasticizers significantly reduce slump loss, demonstrate excellent compatibility with cement, and lower shrinkage rates. This results in more aesthetically pleasing solid structures and makes them suitable for diverse construction requirements.

Cost Savings and Environmental Economics

By utilizing polycarboxylic superplasticizers with high water-reduction rates, the water-binder ratio of concrete is significantly reduced. This innovation creates favorable conditions for incorporating substantial amounts of various mineral admixtures. This approach not only reduces costs for ready-mix concrete producers and decreases cement consumption—thereby conserving national energy resources—but also lowers the hydration heat of concrete. Simultaneously, this technology maximizes the utilization of industrial byproducts such as fly ash, slag powder, zeolite powder, and steel slag powder, offering both environmental and economic benefits. More importantly, the substantial incorporation of mineral admixtures substantially enhances the long-term durability of the concrete.

When using polycarboxylic superplasticizer, observe the following precautions:

(1) Do not mix with other admixtures, especially naphthalene-based water-reducing agents, as this will impair performance. Therefore, ensure storage tanks are thoroughly cleaned before use. If a mixer truck previously loaded concrete with naphthalene-based water-reducing agents, the mixing drum must be thoroughly cleaned before production.

(2) Although concrete mixed with naphthalene-based water-reducing agents and polycarboxylic superplasticizers can be placed together into concrete structures, ensure they are not mixed during use to prevent compromising concrete performance.

(3) Polycarboxylic superplasticizers are corrosive. Prolonged contact with iron may produce odors and cause color changes in the admixture. Therefore, avoid prolonged direct contact with iron containers during use.
