Modified Lignosulfonates Global Superplasticizers for Long Slump Retention

The Modified Lignosulfonates represent a foundational and economically important class of water-reducing admixtures, derived from the lignin recovered during the sulfite pulping process for paper production. In their raw form, lignosulfonates are complex, natural polymers that act as low-range water reducers or plasticizers. While effective, they have inherent limitations, including a tendency...
