Sodium lignosulfonate used as water reducing agent

Ligosulfonate is a water-soluble multifunctional polymer electrolyte, is a lignosulfonate, with dispersing biological slime, dirt iron oxide, calcium phosphate ability, but also zinc ions, calcium ions to form a stable network compound. Lignosulfonate and calcium lignosulfonate commonly used in the multi-purpose concrete waterproofing agent superplasticizer, concrete after adding water reducer, superplasticizer hydrophobic groups directed adsorbed […]

Calcium Lignosulfonate work as water-reducing agent

Calcium Lignosulfonate in the concrete water-reducing mechanism of enhancement of calcium lignin sulfonate and lignin sulfonate superplasticizer is an appearance of the active agent, to participate in the concrete, the hydrophobic group as directed adsorbed on cement particles appearance, so that a negative charge of cement. Cement particles having the same charge in the charge repulsion […]

Function of Lignosulfonate

Function of Lignosulfonate Ligno sulfonate ( sodium lignosulfonate ) pulping process of bamboo wood and straw extract, modification reaction was concentrated and spray- drying. Product is light yellow ( brown ) free flowing powder, soluble in water, chemically stable, long-term sealed storage without decomposition. Lignin series is a surfactant , can be modified , processing […]

Calcium lignosulfonate uses in concrete

Calcium lignosulfonate in concrete action and dosage – Stone Refractories I. Calcium lignosulfonate water reduction in concrete reinforced role Calcium lignosulfonate and sodium lignosulfonate reducing agent is a surface-active agent, added to the concrete, due to the orientation of hydrophobic groups adsorbed on the surface of cement particles, so that the cement with a negative […]

Lignosulfonate used in concrete

Usage of lignosulfonates on the base of sodium, relating to the hydrofilizing plastificators, at the concrete manufacture and dry construction mixtures lets to reduce the consumption of components up to 10-15%. Demixing of the concrete mass reduces and its solidity rises, the speed of hardening slows down. They insert additives of lignosulfonates in the quantity […]

Caclium lignosulfonate used as water reducing agent in concrete

Caclium lignosulfonate used as water reducing agent in concrete Calcium lignosulfonate is extracted from the wood and straw pulp after sulfite pulping processed by advanced production technology have made of brown powdery solid, highly soluble in water. It is a polymer electrolyte having a molecular weight from the 1,000-100000. 10000-40000 dispersion which is particularly effective, […]
