Sodium Lignosulphonate used as concrete water reducer
Sodium Lignonsulphonate:
Sodium lignosulfonate (sodium salt of lignosulfonic acid) is a natural polymer and anionic surfactant. Its appearance is brown powder or liquid, no special odor, non-toxic, easily soluble in water and lye, precipitated by acid, and has strong dispersing ability. As a kind of surfactant, sodium lignosulphonate can produce multiple products through modification, processing, compounding and other methods, mainly used in concrete, cement, resin, rubber, dye, pesticide, ceramics, asphalt, feed, water treatment , coal water slurry, refractories, oil field drilling, compound fertilizers, smelting, casting, adhesives.
Sodium lignosulfonate can be used as an admixture for polymers and concrete, and has the advantages of low cost, high efficiency, strong market competitiveness and environmental protection. At present, the construction industry is the largest demand for sodium lignosulfonate. That’s because it has excellent properties such as high water-reducing performance, low slump loss, high strength and retardation. And this product can adsorb and disperse cement, and improve various physical properties of concrete. In addition, sodium lignosulphonate powder can be formulated into early strength agent, retarder, antifreeze, pumping agent.

Features of Sodium lignin sulfonate
1, Reduce water consumption by more than 14%.
2, Strong adaptability to various cements.
3, Improve the workability of concrete.
4, Reduce the heat of hydration in the early stage of cement hydration.
5, Chlorine-free and non-corrosive to steel bars.
6, It has an obvious compounding effect with naphthalene based superplasticizer.
7, According to the type of cement, the condition of the aggregate, the type of naphthalene superplasticizer, etc., we need to test and then determine the dosage and ratio.
8, The recommended dosage of sodium lignosulfonate in concrete is 0.2%~0.6% (cement weight), and we should determine the optimal dosage after passing the test.
Packaging and storage
1. Powder products are made of chemical fiber woven bags, lined with plastic film bags, each bag net weight (40±0.2kg) or (25±0.2kg) or (750±0.2kg), can also be customized according to customer requirements.
2. Powder products should be stored in dry and ventilated special warehouse, products such as damp caking can be crushed or dissolved into water agent use does not affect the actual effect.
