Undensified Silica Fume
Dry densified silica fume is the most economical product form for transportation, as its higher density allows bulk handling methods, and reduced shipping costs. BENEFITS Prevents reinforcing steel corrosion in concrete, due to its extremely low permeability to chloride-ion intrusion and high electrical resistivity.
What is densified silica fume? – Silica Fume for Sale …
Densified silica fume is produced by treating undensified silica fume to increase the bulk density up to a maximum of about 400 to 720kg/m . This increase in bulk density is usually accomplished by tumbling the silica-fume particles in a silo, which causes surface charges to build up.
