Sodium lignin is applied as concrete water reducing admixture and built material of series multifunction high-performance water reducing admixtures. When it is used as water reducing agent in concrete, dosage is 0.2-0.3%. The products can be directly adopted as additive in the concrete. Moreover, they also can be compounded with such high-performance water reducing admixture as naphthalene superplasticizer and sodium gluconate. 

It also can be used in many industry: fertilizer/ceramic/refractory/leather/dye/feedstuff, etc.
