(SiO2). Most micro silica particles are less than 1 micron ( inch) in diameter, generally 50 to 100 times finer than average cement or fly ash particles. Frequently called condensed silica fume, micro silica is a by product of the industrial manufacture of ferrosilicon and metallic silicon in hightemperature electric arc furnaces.

using silica fume on the properties of fresh and hardened concrete made with crushed bricks through experimental investigation. The effect of using silica fume on the workability of concrete due to addition of silica fume was measured by taking the slump of the concrete produced with and without silica fume.
Condensed silica fume is essentially silicondioxide (more than 90%) in noncrystalline form. Since it is an air borne material line fly ash it has spherical shape. It is extremely fine with a particle size less than micron and specific surface area of about 20,000m²/kg. Silica fume is used as an artificial pozzolanic admixture in concrete.
Silica fume consists primarily of amorphous (noncrystalline) silicon dioxide (SiO2). The individual particles are extremely small, approximately 1/100th the size of an average cement particle. Because of its fine particles, large surface area, and the high SiO2 content, silica fume is a very reactive pozzolan when used in concrete.
