Concrete additive Sodium lignosulfonate / sodium lignosulphanate

Overview of Concrete additive Sodium lignosulfonate / sodium lignosulphanate

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 additive Sodium lignosulfonate / sodium lignosulphanate

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 additive Sodium lignosulfonate / sodium lignosulphanate

Sodium lignosulfonate (NaSLON) and sodium lignosulphanate (NaSLN) are both sodium compounds that have been added to concrete as admixtures to improve its strength, reduce shrinkage, and enhance the aesthetic appeal of the finished product. The concentration of these additives in concrete can vary depending on the specific application requirements and the desired properties of the final product. The most common concentrations used for sodium lignosulfonate in concrete include 0.1%, 2.5%, and 3%. These concentrations correspond to various degrees of flashpoint, transparency, and density, respectively. For example, 0.1% NaSLON is used for wetting purposes, while 2.5% NaSLON is typically used for air-drying concrete construction. It's important to note that the effectiveness of these additives may be affected by factors such as temperature, moisture content, and hydration conditions. Therefore, it's essential to carefully consider these factors when determining the appropriate concentration of sodium lignosulfonate or sodium lignosulphanate in your concrete mix.
