94% Densified Microsilica (Silica Fume) 94D
94% Fumée de silice densifiée ( Microsilica 94D) is a type of silica fume that has been processed to increase its bulk density. This makes it easier to handle and transport, and can also improve its performance in concrete.
94% Fumée de silice densifiée, is a byproduct of the production of silicon and ferrosilicon alloys. It is a highly reactive pozzolan with a high silica content of over 94% and a bulk density of around 550-700 kg/m3. The specific surface area of 94% Densified Silica Fume is very high, ranging from 15,000 à 30,000 m2/kg, making it an ideal supplementary cementitious material for enhancing the strength, durability, and workability of concrete.
