Exceptional Chloride Ion Resistance

RCPT Tested Micro Silica delivers a robust barrier against chloride ion penetration (RCPT value < 1000 Coulombs, ASTM C1202 certified), significantly extending the durability of concrete structures. Its addition helps prevent corrosion in reinforced concrete, making it especially valuable for marine and aggressive environments.

Ultra-Fine Particle Size and High Purity

With an average particle diameter of 0.15 - 0.2 microns and purity over 90% SiO2, this micro silica offers superior filling properties, low porosity, and a fine, amorphous texture. These features result in improved strength, smooth surface finish, and reduced permeability in both standard and high-performance concretes.

Versatile Industrial Applications

Ideal for concrete admixtures, refractory castables, industrial flooring, shotcrete, and repair mortars, this micro silica enhances compressive strength, dimensional stability, and extends service life. Its excellent neutral refractory properties and high melting point (>1600C) make it suitable for demanding high-temperature conditions.

FAQ's of RCPT Tested Micro Silica:

Q: How does RCPT Tested Micro Silica enhance concrete durability?

A: The micro silica dramatically reduces chloride ion penetration (RCPT value < 1000 Coulombs), improving corrosion resistance in reinforced concrete. Its ultra-fine particles fill voids, resulting in denser, less permeable concrete with increased compressive strength and extended lifespan.

Q: What are the industrial applications of this micro silica?

A: This micro silica is used as a concrete admixture, refractory castable, in industrial flooring, shotcrete, and repair mortars. Its properties increase strength, thermal stability, and chemical durability, making it ideal for harsh, aggressive, or high-temperature environments.

Q: When and how should RCPT Tested Micro Silica be added in concrete or refractory production?

A: Add the micro silica during the mixing process, preferably with other fine admixtures or after coarse materials. Its addition should follow precise dosage recommendations for optimal workability, strength improvements, and enhanced durability.

Q: Where is the micro silica manufactured and supplied from?

A: This product is manufactured and supplied in India and is available in standard packaging options of 25 kg, 50 kg, and jumbo bags for easy bulk handling and storage.

Q: What is the recommended storage process for this product to retain its effectiveness?

A: Store the micro silica in its original sealed packaging, in a dry, moisture-free environment. Proper storage ensures a shelf life of up to 24 months from the date of manufacturing.

Q: What benefits does micro silica offer in refractory and high-temperature applications?

A: Thanks to its high melting point (>1600C), low porosity, and neutral refractory nature, the micro silica maintains dimensional stability and integrity at elevated temperatures, making it suitable for both high-performance refractories and demanding industrial settings.
