It consists of very fine, amorphous silicon dioxide (SiO₂) particles that are collected from the flue gases of electric arc furnaces. Microsilica is used as a supplementary cementitious material in concrete and other applications due to its high pozzolanic reactivity and particle fineness. - **Product Category:** Abrasive & Material - **Key Features:** - **Fine Particle Size: **Microsilica particles are extremely fine, typically ranging from 0.1 to 1.0 micrometers, providing a high surface area for chemical reactions. - **High Pozzolanic Reactivity: **Reacts with calcium hydroxide in cement to form additional calcium silicate hydrate, improving the strength and durability of concrete. - **Enhanced Durability: **Improves the durability and resistance of concrete to environmental factors such as moisture, chemicals, and high temperatures. - **Low Bulk Density: **The fine particles result in a low bulk density, which can enhance the workability and consistency of concrete mixtures.
