About Silica Fume
Silica Fume, also known as microsilica, is an amorphous polymorph of silicon dioxide. Its primary industrial value lies in its extreme fineness and high silica content, which allows it to act as a powerful pozzolan in cementitious systems, reacting with calcium hydroxide to form additional calcium silicate hydrate (C-S-H) gel.
In the Indian market, Silica Fume is extensively utilized in large-scale infrastructure projects, including bridges, dams, and high-rise buildings, to achieve high compressive strength and low permeability. It is also a critical component in the manufacturing of high-performance refractory bricks and castables for the steel and cement industries across India.
When procuring Silica Fume in India, buyers should prioritize suppliers who provide consistent SiO2 content and bulk density specifications. It is recommended to verify the source of the material, as the manufacturing process significantly influences the reactivity and performance of the fume in concrete applications.

Frequently Asked Questions
What is the price of Silica Fume in India?
Silica Fume prices in India vary by grade, order quantity and delivery location, and move with market conditions. To get the current price for your requirement, submit an enquiry on Chemical Dekho and receive verified quotes from suppliers and manufacturers within 24 hours.
What is the difference between densified and undensified silica fume?
Densified silica fume is easier to transport and handle due to higher bulk density, while undensified is lighter and often preferred for specific dry-mix applications.
Does silica fume affect concrete setting time?
Yes, it can accelerate the initial set, often requiring the use of water-reducing admixtures or superplasticizers.
Is silica fume hazardous to handle?
It is not chemically toxic, but the fine dust is a respiratory irritant, requiring the use of dust masks during handling.
How does it improve concrete durability?
It fills the microscopic voids between cement particles, significantly reducing permeability and increasing resistance to chemical attack.
Can I use silica fume in all types of concrete?
It is primarily recommended for high-strength or high-performance concrete where specific durability or strength requirements are needed.
