Powder silica fume for the realisation of high performance concrete. Prevents segregation.
- Ultrafine and micrometric silica from plants producing silicium
- Introduced in concrete with hydraulic binder, CHRYSO® Silica behaves like a pozzolan. Its fineness creates a huge reactivity with cement.
- It improves the cohesion and compacity of concrete, and prevents segregation.
- CHRYSO® Silica:
- improves long term strengths of concrete, - eases pumping of concrete, even with a low ratio of cement,
- improves durability of concrete in agressive environment,
- improves freeze-thaw resistance.
Domains of application
