Calcium lignosulfonate, referred to as wood calcium,  is a multi-component high molecular polymer anionic surfactant. Its appearance is light yellow to dark brown powder with a slight aromatic odor. It is easily soluble in water and has good stability. Its molecular weight is generally between 800 and 10,000, and this product has strong dispersibility, adhesion and chelating properties.

Most importantly, calcium lignosulphonate has a very wide range of uses, such as concrete water reducers, industrial detergents, pesticides and insecticides, herbicides, dye diffusing agents, coke and charcoal processing, petroleum industry, ceramics, wax emulsions, etc.

  • Used as a concrete water reducer: it can improve the workability of concrete and improve the quality of the project. It can be used in summer to suppress slump loss, and it is generally used in combination with superplasticizers.
  • Used as a mineral binder: in the smelting industry, calcium lignosulfonate is mixed with mineral powder to form mineral powder balls, which are dried and placed in the kiln, which can greatly increase the smelting recovery rate.
  • Refractory materials: When making refractory bricks and tiles, calcium lignin sulfonate is used as a dispersant and adhesive, which can significantly improve the operating performance, and has good effects such as water reduction, strengthening, and prevention of cracks.
  • Ceramic industry: Calcium lignosulfonate is used in ceramic products, which can reduce the carbon content and increase the green strength, reduce the amount of plastic clay, have good mud fluidity, and increase the finished product rate by 70-90%.
  • Used as a feed binder: it can improve the preference of livestock and poultry, with good particle strength, reduce the amount of fine powder in the feed, reduce the powder return rate, and reduce the cost.
  • Others: it can also be used in refining auxiliary, casting, pesticide wettable powder processing, briquette pressing, mining, beneficiation agent, road, soil, dust control, tanning and leather filler, Carbon black granulation and other aspects.

As the main component of concrete water reducer, calcium lignosulfonate can effectively reduce the mixing water consumption of concrete and improve the fluidity and working performance of concrete. Its mechanism of action is mainly reflected in the following aspects:

First, calcium lignosulphonate changes the charge distribution and surface properties of cement particles by adsorbing on the surface of cement particles, so that the electrostatic repulsion between particles is enhanced, thereby achieving uniform dispersion of cement particles.

Secondly, the dispersing effect of calcium lignin sulfonate helps to reduce the pores and microcracks in concrete and improve the density and strength of concrete. At the same time, the released free water can participate in the hydration reaction in concrete and promote the hardening process of concrete.

Finally, this product can also improve the workability of concrete, improve the construction performance of concrete, reduce the pumping resistance of concrete, and reduce energy consumption and cost.
