The product comes in standard 25 kg bags, with flexible packaging options available to meet specific requirements. For optimal shelf life of up to 2 years, Nano Silica should be stored in a cool, dry environment, away from moisture. Handling is safe and straightforward, as the powder is non-toxic, odorless, and stable under normal storage and transport conditions.

FAQ's of Nano Silica:

Q: How is Nano Silica Powder typically used in construction applications?

A: Nano Silica Powder is incorporated into concrete, mortar, and coatings to enhance strength, durability, and workability. It improves the compressive and flexural strength of materials, reduces permeability, and aids in achieving high-performance construction products.

Q: What benefits does Nano Silica offer over conventional silica materials?

A: With its ultra-fine particle size (10-20 nm) and high surface area, Nano Silica increases pozzolanic activity, providing superior mechanical properties, reduced porosity, improved durability, and greater resistance to chemicals and heat compared to traditional silica.

Q: Where should Nano Silica Powder be stored to maximize shelf life?

A: To ensure a 2-year shelf life, Nano Silica should be stored in a cool, dry place, away from moisture and direct sunlight. Proper storage helps maintain its stability and prevents agglomeration.

Q: When is Nano Silica added during processing in concrete production?

A: Nano Silica is typically mixed with other admixtures during the batching process prior to adding water. This ensures uniform dispersion and optimal performance of the powder in the final mix.

Q: What is the process for handling and mixing Nano Silica safely?

A: Nano Silica is a non-toxic, odorless powder, making it safe to handle using standard industrial precautions. To ensure efficient dispersion and prevent dust formation, it is advised to add it gradually to mixes and use suitable personal protective equipment when handling large quantities.

Q: What is the minimum order quantity and available packaging for this product?

A: The minimum order quantity for Nano Silica Powder is 500 kg, and it is available in standard 25 kg bags or customized packaging as required by the customer.
