LigniOx lignins: High performance concrete plasticizers and versatile dispersants

Abstract

A simple and economic alkali-O2 oxidation (LigniOx) process has been developed for the production of concrete plasticizers and versatile dispersants from technical lignins. Previously, soda and kraft lignin based LigniOx lignins have been shown to have great potential to serve the traditional lignosulfonate markets, and to compete even with more expensive synthetic products. Here, the latest results of successful use of kraft, organosolv and hydrolysis lignin based LigniOx solutions for mortar plasticization in comparison to several commercial lignosulfonates and synthetic superplasticizers are presented. To widen the range of applications of LigniOx lignins, high performance for dispersing of special carbon black into aqueous solutions, used e.g. in paints, inks and various coatings is demonstrated.
