  • What is ligniox lignin?
  • The LigniOx plasticizers enable the use of a small amount of water, producing a highly workable concrete that hardens into a strong final product. In fresh concrete, the LigniOx lignin works noticeably better than a commercial lignosulphonate-based plasticizer and even competes with some of the synthetic superplasticizers.
  • Does ligniox lignin work in concrete?
  • In fresh concrete, the LigniOx lignin works noticeably better than a commercial lignosulphonate-based plasticizer and even competes with some of the synthetic superplasticizers. The lignin oxidation process is easy to integrate into existing biorefineries owing to compatible and safe bulk chemicals.
  • What is ligniox innovation action?
  • The aim of the LigniOx Innovation Action is to demonstrate the techno-economic viability of alkali-O2 oxidation technology (LigniOx) for the conversion of variable lignin-rich side-streams into versatile dispersants, and especially high-performance concrete and mortar plasticizers.
  • What is ligniox used for?
  • In addition to concrete plasticizer, LigniOx lignins can also be used as a dispersing additives, e.g. in paints, coatings, and in the manufacture of gypsum products. Concrete is the most used construction material, and good workability of fresh concrete must be ensured without compromising the strength of matured concrete.
  • What is ligniox process?
  • This LigniOx process uses molecular oxygen as environmentally friendly and low-cost oxidizing agent and introduces acidic groups into the lignin polymer, converting it into a water-soluble polyelectrolyte.
  • Can alkali oxidation convert lignins to versatile dispersants?
  • A simple and cost-efficient alkali oxidation process for conversion of technical as well as biorefinery lignins to versatile dispersants, particularly high performance concrete superplasticizers, has been developed by VTT.
