Micro Silica, also known as Silica Fume, is a highly reactive pozzolanic material derived as a byproduct of ferrosilicon and silicon metal production. With silica content typically exceeding 85%, it significantly enhances the strength, durability, and chemical resistance of concrete, mortars, and refractory formulations. Widely traded internationally for use in high-performance construction, shotcrete, oil well cementing, and advanced ceramics applications, Micro Silica commands steady demand in global building material markets. Offered in both densified and undensified forms to suit various processing requirements.
