Silica fume consists of amorphous silicon dioxide. Each individual particle of silica fume is very small in the order of 1/100 th the size of a cement particle. Silica fume is also used as a filler material in refractory concretes, where its function is to improve the particle packing of the product increasing strength and reducing porosity.
