Lignosulfonate Lignin is used producing concrete and cement slurry

lignosulfonate, commonly known as lignin, is a chemical that is obtained as a by-product of wood pulping. Its compound composition makes it versatile in a wide array of industrial applications. Some of them include:

Building and Construction

Sodium lignosulfonate has been used for many years in the construction industry. This is because it is eco-friendly and also due to its stabilising features. The chemical is used when producing concrete and cement slurry. It aids in reinforcing mechanical strength and final resistance. Thus, it delivers durable building structures.

For over thirty years, Bisley Company has been a principal supplier of Lignosulfonates. Currently, we have partnered with Domsjo in the supply of Sodium Lignosulfonate. We supply the chemical to admixture companies across Australia, Asia, New Zealand, and the Middle East.

Water Reduction

Lignosulfonate has water reducing ability due to its surfactant properties. This is whereby an organic compound possesses both hydrophilic and hydrophobic molecules. These features enable water reduction by releasing excess water between the particles.

At Bisley, we supply Lignosulfonate to construction companies, which prefer it due to its water reduction ability. By reducing concrete hydration, it escalates compactness and boosts its impermeability. Its simple and inexpensive water-reducing results have made it applicable in numerous domestic constructions.

Soil Stabilisation

Nowadays, engineers and agricultural experts have majored in soil stabilisation using chemicals. However, Lignosulfonate has stood out as the most effective soil stabilising chemical. Its dominance has been enriched by its ability to coalesce soil particles tightly, enhancing waterproofness.

Some Lignosulfonate tests have been conducted on silty soils, and the results showed improved wet-dry resistance. It also boosted the bonding between soil particles. Road constructors have recently maximised the use of Lignosulfonate in designing public and private roads. Its incorporation into the construction industry has resulted in reduced road construction and maintenance costs and outstanding final road results.

Ceramic Applications

Lignosulfonate possesses molecular compositions that can be altered by the addition of other chemical components. This makes it possible to enhance the mechanical green and dry strength in the production of ceramics. It is also a vital component as it reduces mudflow and improves adhesive properties. Additionally, it is used to curb shrinkage, which enhances ceramic durability.

It is also useful in the extrusion or pressing stage since it serves as a lubricant. Lignosulfonate makes the production of ceramics relatively inexpensive and long-serving.

Pellet Binding

We at Bisley, have supplied Lignosulfonates for a wide range of pellet binding applications. For instance:

They are incorporated into animal feeds to improve the quality of feed pellets.

They are also used in carbon black binding. They give surface interactions that spike pellet strength.

Lignosulfonates have also been utilised in coal and coke refining. In these industries, there is a lot of powder that can be expensive to bind. Lignosulfonates can be effective in the binding process as it converts the powder into appropriate handling pellet sizes. Thus, it stands out as a less expensive option in binding pellets.
