FAQ's of Sodium Naphthalene Formaldehyde:

Q: How is Sodium Naphthalene Formaldehyde used in concrete applications?

A: Sodium Naphthalene Formaldehyde is primarily added to concrete as a superplasticizer. It is mixed with other ingredients during batching, usually in a dosage of 0.5-1.2% of the cement weight, to enhance workability, flowability, and strength without increasing water content.

Q: What are the benefits of using this product in construction projects?

A: This superplasticizer offers high water-reducing capabilities, improved concrete workability, increased early and final strength, and better surface finish. Being non-toxic and biodegradable, it also aligns with eco-friendly construction practices.

Q: When should Sodium Naphthalene Formaldehyde be added during the concrete mixing process?

A: It should be incorporated during the initial mixing phase, either dispersed in water or directly added to the mix, ensuring even distribution for optimal performance and maximum water reduction.

Q: Where is this admixture typically applied?

A: Sodium Naphthalene Formaldehyde is suitable for ready-mix concrete, precast and prestressed structural elements, and other advanced concrete construction, making it ideal for infrastructural, commercial, and residential projects.

Q: What is the correct storage process for Sodium Naphthalene Formaldehyde?

A: Store the product in a cool, dry, and well-ventilated area, away from direct sunlight. The powder should remain in its original sealed packaging (25 kg or 50 kg plastic woven bags) to avoid moisture absorption and maintain shelf life.

Q: Is this product compatible with other admixtures and how does compatibility affect results?

A: Yes, Sodium Naphthalene Formaldehyde is compatible with a variety of other concrete admixtures. Compatibility ensures that different additives can work together to enhance concrete performance without negative interactions.

Q: What are the environmental and safety considerations of using this superplasticizer?

A: The product is non-toxic, non-poisonous, non-corrosive, and biodegradable. It supports environmentally responsible construction, poses minimal risk to health and the environment, and is safe for regular use on site.
