Sodium lignosulfonate, identified by CAS 8061-51-6, is a water-soluble anionic polymer derived from wood pulp processing that functions as a highly effective dispersing agent and surfactant. This industrial ingredient acts as a concrete admixture water reducer by adsorbing onto cement particles, creating electrostatic repulsion that prevents agglomeration and enhances the workability of cementitious pastes without increasing water content. Beyond construction chemistry, lignosulfonic acid sodium salt serves as a primary binder and stabilizer in industrial granulating and pelletizing processes to improve the structural integrity of processed materials. We provide professional support for this material with competitive factory pricing and customized specifications to meet diverse formulation requirements. Every shipment is accompanied by complete technical documentation, including MSDS, TDS, COA, ensuring reliable bulk supply for large-scale industrial manufacturing.

Product Description
Uses and characteristics: Sodium lignin sulfonate superplasticizer, chemically modified by sulfite pulping waste liquid, with medium molecular weight, low reducing sugar content, used for concrete admixture, with low dosage, low gas content, strong adaptability to cement, characterized by compounding with naphthalene high-efficiency superplasticizer, the liquid admixture made is not deeply produced.
a) Water consumption can be reduced by more than 14%.
b) Significantly improve the workability of concrete.
c) It can greatly reduce the hydration heat in the early stage of cement hydration.
d) It does not contain chlorine salts and has no corrosive effect on steel bars.
e) Free of alkali active substances.
Main properties: a) Sodium lignin sulfonate water reducer, the recommended amount in concrete is 0.2%~0.6% (cement weight), and the user should determine the dosage through experiments. b) Sodium lignin sulfonate superplasticizer can be used as a liquid. c) Sodium lignin sulfonate superplasticizer, the compounding effect with naphthalene high-efficiency superplasticizer is obvious, the dosage and ratio should be determined by the user according to the variety of cement used, the aggregate situation, and what kind of naphthalene high-efficiency superplasticizer is used after experimentation.
Precautions: a) When using sodium lignin sulfonate superplasticizer, strictly control the dosage, if it is less, the effect will not be obvious, and if it is too much, it will affect the early strength. b) When the temperature is lower than 5 °C, it is not suitable for general concrete engineering to be used alone. c) Before use, the parameters of use should be determined by experimentation.
FAQ - Technical & Supply Chain
-
Q:
Does Sodium Lignosulfonate CAS 8061-51-6 maintain consistency with different cement types?
A: Yes, this substance is chemically defined as a sulfonated wood lignin sodium salt and is specifically utilized as a universal plasticizer. Its molecular structure ensures consistent surface-active properties across various Portland cement grades and industrial mineral suspensions, facilitating predictable flow characteristics in large-scale formulations. -
Q:
What is the specific role of this ingredient in ceramic and refractory manufacturing?
A: In ceramic processing, sodium lignosulfonate is applied as a temporary organic binder and deflocculant. It reduces the viscosity of ceramic slips and improves the green strength of molded parts by enhancing particle packing efficiency, which is essential for maintaining dimensional stability during the drying and firing stages of industrial production.
