Silica Fume – An Admixture for High Quality Concrete
Silica fume is one such pozzolanic material. Silica fume is a by product obtained from the reduction of high – purity quartz with coal or coke and wood chips in an electric arc furnace during the production of silicon metal or silicon alloys. The use of Silica fume as admixture in concrete has opened up one more chapter on the advancement

SCMs in Concrete: Silica Fume
Jul 10, 2017Silica 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.
