Liquid lignin can be used as a concrete water-reducing agent (water reduction rate: 8-9%), while also serving as a retarder, early strength enhancer, air-entraining agent, dust suppressant, mineral cementing agent, pumping aid, and grinding aid.
Performance Enhancement: At optimal dosage, water reduction reaches 9-11%. Strength improvement: 3/7-day strength increases by 20-30%, with 28-day and long-term strength rising 15-20%.
Workability Improvement: Maintains water content while enhancing flowability and workability.
Cement Savings: Achieves 8-10% cement reduction while maintaining slump and strength.
Retarding Effect: Extends initial/final setting times by over 3 hours and delays peak hydration heat by 5 hours. Ideal for summer construction, ready-mix concrete transport, and mass concrete projects.
Air-Entraining Function: Improves concrete freeze-thaw resistance.
Safety: Non-corrosive to reinforcing steel and aggregates.
