Naphthalene Superplasticizer is mainly composed of β-naphthalene sulfonic acid formaldehyde high condensate, which has the functions of non-air entraining, superplasticization, efficient water reduction and enhancement.
Naphthalene Superplasticizer has strong adaptability to cement low content. It is easy to use, so it is especially suitable for regular and steam-cured concrete with high efficiency water-reducing and strengthening requirements. It can also be used as the parent material of composite concrete admixture.
Naphthalene Superplasticizers can be widely used in pumping concrete, high-strength precast and prestressed concrete, mass concrete, centrifugal concrete, etc.

1)Naphthalene Superplasticizer has obvious water-reducing and dispersion effects, with a water-reducing rate of 15% and 25%, which can improve the fluidity of cement paste under the condition of low water-cement ratio.
2) Superplasticization can effectively increase the fluidity of concrete and reduce bleeding and segregation, thus improving the workability of concrete, easy construction and easy compaction.
3) The enhancement effect is good
Under the condition of the same amount of cementitious material per unit, the 1D, 3D, 7d, 28d and 90d compressive strength of concrete mixed with superplasticizer can generally increase by 60%, 50%, 40% and 41% compared with the standard concrete in the same period.
4) The product has strong adaptability
The product is suitable for various specifications and types of cement and is compatible with admixtures such as expansive agents, air entraining agents and active admixtures such as fly ash. It has good adaptability, functions complement and excite each other, and can improve concrete's main physical and mechanical properties in an all-around way. The compactness, water resistance and wear resistance of concrete are greatly improved.
5)The setting time is suitableThe product has little effect on cement's initial and final setting time, and the setting time difference is generally within 1 hour.
6)The product has good safety performance
Non-toxic, non-irritating and radioactive, does not contain substances dangerous to rust steel bars; non-flammable, explosive, non-dangerous goods.
Usage and points for attention
1) Dosage: the range of content of this product is powder 0.3% mi 1.5%, commonly used content is 0.5-1.0%.
The amount of liquid added is converted according to the actual concentration of the liquid, which can provide a liquid concentration range of 30% to 40%.
2)Mixing method: easy to use. Solid products can be used directly and dissolved in water to form a solution-type admixture to meet the requirements of various occasions or mixers.
For some construction processes with special requirements, such as long-distance transportation or transportation, it can also be added 15-20 seconds behind the mixing water in the mixing process, making the effect of the admixture more significant.
3)Accurate measurement and appropriate extension of mixing time, especially powder products, to ensure that admixtures are uniformly dispersed in concrete.
4)Strengthen maintenance. Concrete should be covered and watered immediately after the final setting.
Preface covering should be taken in winter construction to prevent surface frost damage.
According to the specification, the secondary coating should be carried out in time for large-flow concrete.

How to choose a suitable naphthalene superplasticizer?
Answer: Choosing a suitable naphthalene superplasticizer requires considering factors such as engineering requirements, raw material properties, and construction environment. You should choose a brand of naphthalene-based water-reducing agent with appropriate water reduction rate and dosage, and pay attention to its compatibility with raw materials such as cement, sand and gravel. At the same time, product quality and supplier reputation should be considered.
What issues should we pay attention to when using naphthalene superplasticizer?
Answer: When using naphthalene superplasticizer, attention should be paid to controlling the dosage and water consumption to avoid excessive or insufficient effects on the performance of the concrete. At the same time, attention should be paid to the quality stability of the water-reducing agent and avoid using expired or damp products. During transportation and storage, moisture-proof measures should be taken.
What impact does naphthalene superplasticizer have on the performance of concrete?
Answer: Naphthalene superplasticizer has a significant impact on the properties of concrete. It can reduce the amount of mixing water and improve the strength indicators such as compression and flexural resistance of concrete. At the same time, the fluidity and workability of concrete are improved, making it easier to pour and compact. In addition, naphthalene-based water reducing agents can also improve the durability and impermeability of concrete.
How is the compatibility of naphthalene superplasticizer with other admixtures?
Answer: Naphthalene superplasticizer has good compatibility with other admixtures and can be used in combination with other types of admixtures. However, care should be taken to avoid mixing it with some admixtures that have conflicting chemical properties to prevent adverse reactions. Tests should be conducted before use to ensure compatibility meets requirements.
How to solve the problems in using naphthalene superplasticizer?
Answer: In the process of using naphthalene high-efficiency water-reducing agent, if you encounter problems such as excessive bleeding of concrete and excessive slump loss, you can appropriately adjust the mix ratio and add retarder to solve the problem. At the same time, strengthening raw material quality control and construction process supervision are also important measures to ensure the effectiveness of use.
