Production Description
Sodium lignosulfonate(Sodium lignosulphonate) is yellow brown powder completely water soluble,is naturally anionic surfactant of high molecular polymer, rich in sulfo and carboxyl group and has better water-solubility, surf-activity and dispersion capacity.Naturally work as anionic surface active substances, on the adsorption and dispersion of cement, concrete can improve various physical performance. Reusable dubbed early strength agent, retarder, antifreeze, pumping agent, and naphthalene superplasticizer compound made of liquid admixtures basically no precipitate.

Sodium Lignosulfonate Uses
1.Sodium Lignosulfonate superplasticizer dosage of cement content 0.20-0.30%, commonly used dosage is 0.25% water reduction of up to 9-11%. In the appropriate dosage when compared with the reference concrete strength increased by 15-20% 3 days, 7 days strength increased 20-30%, 28 days by 15-20%, long-term strength also increased.
2.Without changing the water in the case of concrete( suggested ratio 0.65)1to increase the flow of concrete, improved work-ability.
3.In keeping concrete slump, the same intensity and the reference concrete, cement can save 8-10%, the use of one ton of Lignosulfonate superplasticizer powder, can save 30-40 tons of cement.
4.In the standard state, concrete mixed with this agent may delay compared with the reference concrete setting time of concrete more than 3 hours, the final setting time of 3 hours, the peak heat of hydration delayed more than five hours, is conducive to summer construction and commodity concrete transport and mass concrete.
5.Sodium Lignosulfonate superplasticizer with micro-entraining, can improve the impermeability of concrete freeze-thaw performance.
6.After the agent mixed concrete and aggregates of reinforced non-corrosive.
7.Increase its water dispersion capacity to avoidwater bubble inside the slump.
Scope
Suitable for concrete, high fluidity concrete, pumping concrete, concrete products and concrete construction in summer as well as retarding the special requirements of concrete, concrete piles, concrete piles sink, hand-dug piles of concrete and underground bulk concrete construction, with good economic benefits.
Sodium Lignosulfonate Applications
- Concrete Admixture:
- Sodium lignosulfonate is widely used as a concrete admixture, where it acts as a plasticizer and water reducer.
- It helps to improve the workability and fluidity of concrete mixes, allowing for a reduction in the amount of water needed.
- This can lead to increased concrete strength, reduced porosity, and improved durability of concrete structures.
- Cement Grinding Aid:
- Sodium lignosulfonate is used as a grinding aid in the production of Portland cement and other hydraulic cements.
- It helps to disperse cement particles during the grinding process, increasing the efficiency and reducing the energy required for cement production.
- The use of sodium lignosulfonate as a grinding aid can also improve the fineness and particle distribution of the cement, leading to enhanced performance.
- Mortar and Plaster Additive:
- Sodium lignosulfonate is added to mortar and plaster mixes to improve their workability, adhesion, and water retention properties.
- This can help to enhance the application and curing of these construction materials, leading to better overall performance and aesthetics.
- Soil Stabilization:
- In earthworks and soil stabilization applications, sodium lignosulfonate is used as a binder and dispersant.
- It helps to bind soil particles together, improving the strength and stability of the soil, particularly in areas with high silt or clay content.
- This can be beneficial for the construction of roads, foundations, and other infrastructure projects in areas with challenging soil conditions.
- Dust Control:
- Sodium lignosulfonate is used as a dust suppressant in construction sites, unpaved roads, and other areas where dust control is a concern.
- It helps to bind and stabilize fine particles, reducing dust emissions and improving air quality in these environments.
Sodium Lignosulfonate Usage
1 .Dosage is0.25- 0.50% by weight of cement, recommended dosage of 0.25%.
2.Powder can be added directly to the cement, sand, gravel in the dry mix, even after the addition of water for mixing, stirring time should be extended, to avoid uneven mixing. Powder can be prepared in advance a certain concentration of the solution, in liquid form to join, but attention should be deducted from the total water consumption of concrete.
3.Users when using this product according to the specific construction conditions (construction season, construction materials, etc.) with reference to the description of the concrete mix to make the necessary tests to obtain the best results.
4.In construction, sodium lignosulfonate is mainly used as a water-reducing agent in concrete and cement formulations. By adding it to the mixture, the amount of water required to achieve a workable consistency is reduced, resulting in a stronger and more durable concrete with improved workability.
5.Sodium lignosulfonate is also used as a dispersing agent for cement, clay, and other mineral powders. It helps to prevent the clumping and settling of particles, resulting in a more consistent and uniform mixture.
5.Furthermore, sodium lignosulfonate is sometimes used as a set retarder in concrete formulations. This means that it slows down the setting time of the concrete, which can be useful in certain construction applications where a longer working time is required.
