White Silica Fume
for castables and High Performance Concrete
Amorphous white silicon oxide powder is obtained by filtering the dust extracted from silicon metal production in an electric furnace. Silica Fume White has a high SiO2 content and very low impurity levels. Its use in refractory castables and High/ Very High performance concrete improve their mechanical properties and their durability. Its stability to temperatures of 1200ºC and its good sintering properties make it a raw material perfectly adapted for ceramics and refractory castables. Its white color enables its use in aesthetical and decorative civil engineering work.
