Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide. Due to its fine particles, large surface area, and the high silicon dioxode content, silica fume is a very reactive "pozzolan" (forms cementitious properties when mixed with water and calcium hydroxide) when used in concrete.
It is also used widely in the monolithic refactory industry.
