Concrete Additives Sodium Lignosulphonate Powder CAS 8061-51-6 SLS

Overview of Concrete Additives Sodium Lignosulphonate Powder CAS 8061-51-6 SLS

Concrete additives, also known as admixtures, are substances added to concrete during the mixing process to enhance specific properties of the fresh or hardened concrete. These additives serve diverse purposes, ranging from improving workability and durability to accelerating or retarding the setting time and enhancing the strength and finish of the final product. Concrete admixtures play a pivotal role in optimizing concrete performance for various construction applications and environmental conditions.

Features of Concrete Additives Sodium Lignosulphonate Powder CAS 8061-51-6 SLS

1. Workability Improvement: Plasticizers and superplasticizers increase the flowability of concrete without adding water, improving workability and pumpability.

2. Setting Time Control: Accelerators speed up the setting and hardening process, while retarders slow it down, allowing for more time for placement and finishing in hot weather or complex structures.

3. Strength Enhancement: Some additives increase the compressive and flexural strength of concrete, leading to more durable structures.

4. Durability Improvement: Corrosion inhibitors, waterproofing agents, and air-entraining admixtures protect concrete from freeze-thaw cycles, chloride ingress, and chemical attacks, prolonging service life.

5. Color and Finish Enhancements: Pigments and finishing aids can be added to give concrete a desired color or texture.

6. Shrinkage Reduction: Admixtures that reduce the amount of water needed or control evaporation can minimize shrinkage cracking.

Parameters of Concrete Additives Sodium Lignosulphonate Powder CAS 8061-51-6 SLS

Sodium lignosulphonate powder, also known as SLS, is a preservative and antioxidant used in concrete construction to prevent corrosion, weathering, and other types of damage caused by the elements. The formula for SLS is Na2LNO3·H2O, where Na2LNO3 is sodium nitrate and H2O is water. The concentration of SLS can vary depending on the application, but it typically ranges from 0.05% to 2% by weight. The parameter for SLS in this formula is the density of sodium nitrate, which is expressed in g/cm³. The density of sodium nitrate is approximately 9.8g/cm³. Overall, SLS is an important ingredient in the production of concrete and plays a critical role in its longevity and performance. Its effectiveness at preventing corrosion and other forms of damage has made it a popular choice for use in various types of concrete applications, including bridge decks, pavements, and parking lots.
