Naphthalene sulfonate is a byproduct of the reaction between naphthalene and sulfuric acid. It is a white, crystalline solid that is insoluble in water. The compound is used as a component of hydraulic fracturing fluid, drilling muds, concrete, and cement slurry. Many people also use it as a detergent, wetting agent, emulsifier, and dispersant. Let’s take a closer look at why naphthalene sulfonate for concrete is so essential and why the construction industry is ordering this compound in bulk.
What does naphthalene sulfonate do for concrete?
Sodium naphthalene is a concrete admixture that increases the strength and longevity of concrete. It is added to the concrete mix in small amounts, typically 2-3%, and works by improving the binding between the cement and aggregate particles. It has a significantly high water-reduction rate. SNF powder for concrete can reduce the water consumption of the final mix by 25%. It also acts as a superplasticizer, meaning it can reduce segregation and water penetration and increase concrete fluidity. As a result, concrete that contains polynaphthalene sulfonate is less likely to crack or crumble over time.
In addition, naphthalene sulfonate for concrete can protect concrete structures from freeze-thaw damage, making it an ideal choice for areas that experience harsh winters. While the compound does add to the cost of concrete, its benefits make it well worth the investment for many construction projects.
Using naphthalene sulfonate for concrete
Concrete is a versatile building material that is used in a variety of applications, from foundations to sidewalks to floors. While it is strong and durable, concrete can be susceptible to cracking and other forms of damage after a few years. For this reason, many construction companies are choosing to add naphthalene sulfonate to concrete mix, and hence this compound is in high demand in recent years.
Naphthalene sulfonate increases the strength and durability of concrete. It does this by improving the bond between the cement and the aggregate. As a result, concrete that contains naphthalene sulfonate doesn’t usually crack or break down over time. Most importantly, it can protect concrete against weathering and environmental damage. Make sure that you use up to 3% of naphthalene sulfonate and not more in your concrete mix.
Benefits of naphthalene sulfonate for concrete
As already mentioned, this compound prevents the formation of cracks in your concrete structure. This would make the structure less likely to break over time. Moreover, compared with sodium lignosulfonate water reducer, SNF superplasticizer makes concrete more water-resistant. This is especially beneficial in areas that experience heavy rains or flooding. By preventing water from seeping into the concrete, NSF helps to prolong the life of the structure. This makes concrete treated with PNS powder an ideal choice for a variety of applications in the construction industry.
Here are a few more benefits of this compound:
● Strengthening – SNF is a key ingredient in concrete that helps to make it strong and long-lasting. The molecules of this compound bind together with the calcium ions in the concrete, forming a strong bond that holds the concrete together. It also prevents the growth of algae and other organisms that can weaken the concrete.
● Water-reduction rate – The water-reduction capability of naphthalene sulfonate reduces the water content of concrete without affecting its strength or durability. This can be a significant advantage when working with large projects, as it can save time and money. Naphthalene sulfonate is also relatively inexpensive, making it an attractive option for many builders.
Naphthalene sulfonate（https://www.chemategroup.com/sodium-naphthalene-sulfonate/） has now become a common additive to concrete that is purported to improve the curing process and reduce cracking. Using sulfonated naphthalene for concrete as an admixture will lead to increased compressive and flexural strength, improved abrasion resistance, and reduced permeability.
