  • What is calcium lignosulfonate?
  • 1. Summary Calcium lignosulfonate (40-65) is an amorphous light-yellow-brown powder obtained from the sulfite pulping of softwood. The organic framework of the additive is a sulfonated random polymer of three aromatic alcohols: coniferyl alcohol, p-coumaryl alcohol, and sinapyl alcohol, of which coniferyl alcohol is the principle unit.
  • Are lignosulfonates a sustainable superplasticizer?
  • Lignosulfonates are promising materials for the production of sustainable superplasticizers. Chemical functionalities of lignosulfonates offer a wide range of structural modifications. In concrete technology, superplasticizers (SPs) are commonly used to reduce water content in concrete admixtures.
  • What are the impurities in calcium lignosulfonate (40-65)?
  • Impurities in calcium lignosulfonate (40-65) include monosaccharides from wood cellulose, sulfite residues, and potentially arsenic and various metallic elements.
  • Can lignosulfonat be used as a biobased SP?
  • In this context, lignosulfonat (LS), renewable byproducts of wood pulp production, holds tremendous potential for the synthesis of biobased SPs. The scope of this review is mainly focused on the reported modifications of LS since 2000 with a special attention to the applications of these modifications in the field of concrete industry.
  • How are purified calcium lignosulfonate (CL) fractions obtained?
  • Five purified calcium lignosulfonate (CL) fractions with different mol. wts. were obtained by fractionation using ultrafiltration and dialysis. The influence of mol. wt. on their physicochem. properties was investigated by detg. the properties of five fractions.
  • What is CAC of Sodium lignosulfonate (SL)?
  • (CAC) of sodium lignosulfonate (SL) in water soln., with which a value of 0.38 g L-1 was obtained. Through the detn. of CAC and observation by DLS, the state and dynamics of the formation of the SL micelles were disclosed.
