APPLICATIONS
Silica Fume is a high-reactivity pozzolan widely used to enhance the performance of concrete and cement-based materials.
Its ultra-fine particles significantly improve strength, durability, and density, making it essential for high-performance formulations
· UHPC and HPC production
· High-strength structural concrete
· Industrial floors and abrasion-resistant surfaces
· Precast and prestressed concrete elements
· Shotcrete and repair mortars
· Grouts and specialized binders
· Marine and chemically aggressive environments

PRODUCT OVERVIEW
Silica Fume is an ultra-fine, highly reactive pozzolanic material produced as a byproduct of silicon and ferrosilicon alloy manufacturing.
Its extremely small particle size and high amorphous silica content significantly enhance the performance of cementitious systems by improving density, reducing permeability, and increasing both early and long-term strength.
Silica Fume is an essential component in UHPC, HPC, and other advanced concrete formulations, delivering superior durability, chemical resistance, and overall structural performance.
