Sodium lignosulfonate is the yellow brown powder, no special smell, non-toxic, easily soluble in water, stable chemical properties, long-term sealed storage without decomposition. What’s more, it has the strong dispersion ability. And it is a anionic surfactant made by wood pulp, with medium molecular weight and low sugar content. As the first generation of concrete water reducer, this product has the characteristics of low cost, low ash, low gas content, environmental friendliness, and strong adaptability to various cements.

Lignin series products are a kind of surfactant, which can produce multiple products through modification, processing, compounding and other methods. Therefore, sodium lignosulfonate is mainly used in concrete water reducing agent, coal water slurry additive, filler in dye industry and pesticide processing and dispersant, binder for powdery and granular materials, used as dilution dispersant, viscosity reducer, etc. in drilling.
(1) Sodium Lignosulfonate in Concrete. As one of the ordinary water reducing admixtures, sodium lignosulfonate can improve its fluidity and plasticity, reduce harmful pores, and significantly enhance the compressive strength of concrete. It can be compounded into accelerator, retarder, antifreeze, pumping agent, etc. If it is used with naphthalene-based superplasticizer, there is no precipitation in the liquid mixture.
As a water reducer, the recommended amount (by weight) of sodium lignosulfonate in concrete cement is about 0.2% to 0.6%. We should determine the optimum amount by experiment. However, the amount of sodium lignosulphonate must be strictly controlled. If the effect is not obvious, this chemical will affect the early strength of the concrete. When the temperature is lower than 5 °C, sodium ligno sulfonate is not suitable for concrete engineering alone.
