Sodium Lignosulfonate, a Concrete Admixture, Is a Sewage Treatment Filler

Sodium lignosulfonate water reducer is a modified powdery low air entraining retarding water reducer. It belongs to anionic surface active substances and has adsorption and dispersion effects on cement, which can improve various physical properties of concrete.

• Optimized Dosage: Recommended dosage is 0.20-0.30% of cement weight, providing 9-11% water reduction.
• Strength Enhancement: 3-day strength increases by 15-20%, and 7-day strength by 20-30%.
• Cement Saving: Saves 8-10% of cement while maintaining equivalent slump and strength.
• Retarding Effect: Delays initial setting time by over 3 hours, ideal for summer construction and large volume concrete.
• Durability: Improves impermeability and freeze-thaw resistance with micro air entraining properties.
• Safety: Non-corrosive to steel bars and aggregates.

Storage Stability: Shelf life up to 1 year when stored in original sealed packaging in a cool, dry, well-ventilated place.

Compatibility: Compatible with anionic and non-ionic dispersants and most organic/inorganic materials.

Packaging Options: Available in 25 kg bags and 625 kg bulk bags.
