Sodium Lignosulphonate (SLS) | amiconcreteplus
Sodium Lignosulphonate (SLS) This is a high purity sodium–lignosulphonate powder product derived from wood. The widespread application of lignosulphonate in ready-mix concrete is attributed to its outstanding dispersing properties. The agglomerates of cement particle are dispersed with small amounts of lignosulphonate.
Sika ViscoCrete-20 HE | PCE based Super-plasticizers
Sika ViscoCrete-20 HE is a liquid admixture for concrete and mortar which is used as high range water reducer or superplasticiser. Sika ViscoCrete-20 HE is designed to work on a combination of electrostatic adsorption and steric repulsion effects allowing solid particles to be effectively dispersed. Therefore a high level of fluidity
Production and Application of Lignosulfonates and Sulfonated Lignin
In this process, sulfomethylation was conducted with 1.2:1 (w/w) sodium hydroxymethyl sulfonate/lignin for 2 h at 100 °C under alkaline conditions. 98 Sodium hydroxymethyl sulfonate was used instead of sodium sulfite. 28 The product was determined to have a lower sulfur content of 4.3 wt % and higher molecular weight of 11 300 g mol 1 than those of commercial lignosulfonates (6.3 wt % and
Sodium lignosulfonate used as plasticizer in concrete
1.Sodium Lignosulfonate uses as 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.

- What is the use of Sodium lignosulfonate as plasticizer in concrete?
- Sodium lignosulfonate used as plasticizer in concrete will reduce the cost by 10-15%,the sodium lignosulfonate could assume 0.5-2% of the total mixture w/w,will increase the strength of concrete by 20-26%. Sodium lignosulfonate uses water reducing agent, By sulfite pulp waste liquid of legal system formed by chemical modification and processing.
- Are lignosulfonates a sustainable superplasticizer?
- Lignosulfonates are promising materials for the production of sustainable superplasticizers. Chemical functionalities of lignosulfonates offer a wide range of structural modifications. In concrete technology, superplasticizers (SPs) are commonly used to reduce water content in concrete admixtures.
- Can superplasticizers reduce water content in concrete admixtures?
- In concrete technology, superplasticizers (SPs) are commonly used to reduce water content in concrete admixtures. Although most of them are fossil fuel-based, some derive from lignosulfonates (LS), that are sustainable and environmentally-friendly polyphenolic crosslinked polymers.
- Can Sodium lignosulfonate water reducing agent be used as liquid?
- Sodium lignosulfonate water reducing agent can be used as liquid. Users can experiment to determine the content and proportion. Using sodium lignosulfonate water reducing agent, Strictly control the content,use less the effect is not obvious,use more affect the early strength of concrete.
- What is the dosage of Sodium lignosulfonate?
- Sodium lignosulfonate uses as water reducing agent,In concrete recommended dosage of 0.2% -0.6% (cement weight meter), Users should determine the optimal dosage through the experiment. Sodium lignosulfonate water reducing agent can be used as liquid. Users can experiment to determine the content and proportion.
- Does calcium lignosulfonate inhibit steel in concrete pore solution?
- Calcium lignosulfonate showed good inhibition for steel in simulated concrete pore solution even after 7200 h immersion. The molecular simulation indicated that sinapyl alcohol in calcium lignosulfonate is the preferred site for accepting electrons. The microscopic ...
