High-Performance & Durable Concrete
Reinforces concrete from within by filling the microscopic gaps between cement particles, resulting in a denser, better-packed mix with higher strength and outstanding impermeability.

Fade-Resistant Color & High Tinting Strength
The specifier's challenge (what problem is solved)
Conventional concrete leaves capillary voids in the cement matrix that let water, chlorides and sulfates migrate through accelerating rebar corrosion and shortening service life.
How it works
(technical mechanism)
Ultra-fine, amorphous SiO2 particles up to 100x smaller than cement grains pack into the gaps between cement particles and react pozzolanically with calcium hydroxide to generate additional C-S-H gel, densifying the matrix and closing the pore network.
Main applications
Enhanced cementitious mortars, Ultra-High-Performance Concrete (UHPC), heavy industrial & civil construction (tunnels, bridges, dams), gypsum board, refractory systems, rubber, glass and polymer compounds
