Sodium Lignosulfonate Construction Grade
Industrial lignin-based water reducer and concrete admixture for concrete, mortar and ready-mix systems.
Sodium Lignosulfonate Construction Grade is a conventional lignin-based water reducer used in concrete admixtures, mortar blends and cementitious formulations that need better workability, practical water reduction and stable batching performance.
This grade disperses cement particles, supports lower water demand and helps improve flow, pumpability and mixing uniformity in concrete and mortar systems.
It is commonly selected for ready-mix concrete, pumped concrete, dry-mix mortar and blended admixture packages where cost-effective workability control matters.
Key Performance Functions
Water Reduction
Supports lower water demand while maintaining practical workability in cementitious systems.
Concrete Workability
Improves flow, pumpability and cement particle dispersion in ready-mix and mortar applications.
Set Control
Provides mild retardation that can help hot-weather pours, long transit and large placements.
Formulation Flexibility
Works as a base component in blended construction admixture packages after compatibility testing.

Recommended Application Areas
| Application Area | Typical Use | Customer Value |
|---|---|---|
| Ready-Mix Concrete | Water-reducing and workability-support additive for commercial concrete. | Improves flow, placement and practical slump control. |
| Pumped Concrete | Dispersing component for concrete requiring stable pumpability. | Supports flowability and more uniform cement distribution. |
| Mass Concrete | Mild retarding aid for large pours and warm-weather construction. | Extends working time and supports hydration heat control. |
| Dry-Mix Mortar | Auxiliary dispersant for mortar and cement-based materials. | Improves mixing uniformity and application consistency. |
| Admixture Compounding | Base lignosulfonate component for blended systems. | Compatible with selected retarders, accelerators and plasticizers after testing. |
Suggested Usage Guidance
| Application | Typical Starting Dosage / Use | Technical Note |
|---|---|---|
| Concrete admixture | 0.25% – 0.50% of cementitious material | Standard starting dosage around 0.25%; confirm by trial mix. |
| Dry addition | Add to dry materials before water | Extend mixing time after water addition to ensure uniform dispersion. |
| Liquid addition | Pre-dissolve before batching | Deduct solution water from total batch water. |
| Site validation | Trial mix required | Dosage depends on cement type, aggregate, temperature and target slump. |
Dosage and application method should be verified by laboratory or pilot testing. Performance depends on raw materials, process conditions, temperature, moisture, mixing time and target technical results.
