SCMs in Concrete: Silica Fume – Precast concrete
Silica fume basics. Silica fume is a byproduct from the production of silicon alloys in an electric arc furnace. The materials are heated to more than 3,600 degrees Fahrenheit in a process that separates silica from the oxygenated silica fume. The process removes the oxygen from the silicon, separating the silica from the oxygenated silica fume.
