The Naphthalene Superplasticizer CAS NO.: 36290-04-7 is a highly efficient water-reducing agent commonly used in the concrete industry, mainly based on sodium naphthalene sulfonate compounds and synthesized through a special chemical reaction.
Features of Naphthalene Superplasticizer
CAS NO.:36290-04-7
Significant water reduction effect
Our products Naphthalene Superplasticizer CAS NO.:36290-04-7 can effectively reduce the amount of cement in concrete, and its water reduction rate can usually reach 25%-30%.
It improves the fluidity and workability of concrete, the amount of water can be greatly reduced, thereby reducing the water-cement ratio and improving the density of concrete.
Improve concrete fluidity
When used, Naphthalene Superplasticizer
CAS NO.:36290-04-7 can increase the fluidity of concrete by about 20%-30%, and the water reduction rate can usually reach 25%-30%. This means that after using our water reducer, under the condition of the same cement content, the moisture content of concrete can be reduced, and the fluidity is improved.
Improve the strength of concrete
After a 28-day curing period, the compressive strength of concrete using Naphthalene Superplasticizer CAS NO.:36290-04-7
can be increased by 15%-30% compared with conventional concrete.
Applications of Naphthalene Superplasticizer CAS NO.:36290-04-7
High-strength concrete production
One of the most notable uses of naphthalene-based high-efficiency water reducers is in the production of high-strength concrete. By reducing the amount of cement, the product can significantly reduce the water-binder ratio (usually by 25%-30%), thereby improving the density and compressive strength of concrete. After using this water reducer, the 28-day compressive strength of concrete can be increased by 15%-30%.
High-performance concrete application
Our water reducer is particularly suitable for the production of high-performance concrete (HPC). High-performance concrete requires a lower water-binder ratio, higher fluidity and longer working time.
Precast concrete component production
It is widely used in the production of precast concrete components. Its excellent dispersibility and water-reducing properties make the concrete have higher fluidity and lower water-binder ratio at the same cement dosage, thereby improving the strength and durability of the precast components.
Self-compacting concrete
Our products are also commonly used in the production of self-compacting concrete (SCC). Self-compacting concrete requires that the mold is filled and compacted by its own weight without vibration.

FAQ
Q: How does Naphthalene-based Superplasticizer work?
A: It works by dispersing the cement particles in the mix, preventing them from clumping together. This reduces the water requirement for a given consistency and increases the concrete's workability, leading to smoother and stronger concrete.
Q: What is the typical dosage of Naphthalene-based Superplasticizer?
A: The typical dosage ranges from 0.5% to 2% by weight of cement, depending on the desired workability and the specific type of concrete mix being used.
Q: Can Naphthalene-based Superplasticizer be used in all types of concrete?
A: Yes, Naphthalene-based superplasticizer is versatile and can be used in various types of concrete mixes, including high-strength concrete, precast concrete, and ready-mix concrete, among others.
Q: What is the difference between Naphthalene-based Superplasticizer and other plasticizers?
A: Naphthalene-based superplasticizer generally offers higher water reduction and better workability compared to conventional plasticizers like lignosulfonates. It also has a stronger dispersing effect, which makes it more effective for high-performance concrete.
Q: Are there any drawbacks to using Naphthalene-based Superplasticizer?
A: One potential drawback is that it can cause excessive air entrainment if not used properly, which may affect the durability of the concrete. Also, improper dosage may lead to a reduction in strength if too much water is added during the mixing process.
Q: Is Naphthalene-based Superplasticizer environmentally friendly?
A: Naphthalene-based superplasticizers are generally safe to use when applied according to manufacturer guidelines. However, their environmental impact depends on the production process. Newer formulations may focus on reducing the environmental footprint.
Q: Can Naphthalene-based Superplasticizer be used with other admixtures?
A: Yes, Naphthalene-based superplasticizer can be used in combination with other admixtures, such as retarders, accelerators, and air-entraining agents. However, compatibility tests are recommended to ensure optimal performance and avoid adverse reactions.
Q: How does Naphthalene-based Superplasticizer affect the setting time of concrete?
A: Naphthalene-based superplasticizer typically has a neutral or slightly retarding effect on the setting time of concrete. The exact impact on setting time depends on the dosage and the specific concrete mix, but it generally allows for longer working times, making it easier to handle during the pouring process.
