Silica fume

Silica fume: a high-performance addition

Through its involvement in the marketing of silica fume for enhancing concrete performance, Condensil has been part of the development of sustainable high-strength and high-performance concretes. Silica fume is a by-product of the production of silicon and ferrosilicon, which are made in an arc furnace through the reduction of quartz with carbonaceous materials at temperatures of 2000°C.
