HR-50 NanoSilica
Category: Pre-market additives

Amorphous silica powder for use as a pozzolan in the cement and concrete industries.

Typical Use:
  • High performance concrete, grouts, overlays, fiber cement and related demanding applications.
  • Architectural concrete applications.
  • As a thickening and thixotropic rheology control agent in cementitious and polymer-containing formulations.
  • As a flow aid additive in the production of industrial mineral powders.
Apparent use of Nanotechnology: amorphous silica (60 nm-300 nm)
Reason for Inclusion:

"Vitro Minerals’ HR-50 NanoSilica is a 100% recycled, fully X-ray amorphous silica, produced by a proprietary high temperature oxidative process. The primary particles, sized between 60 and 300 nm (0.06-0.3 μm), are spherical and form loosely agglomerated micro-clusters up to about 3 μm." -Retrieved 11/20/2020 from
