Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2). Its individual particles are extremely small, approximately 1/100th the size of an average cement particle. It therefore effectively fills in empty pores in the cement and helps produce a stronger, more compact material.

When silica fume is added to concrete, initially it remains inert. Once portland cement and water in the mix start reacting with each other (hydrating), primary chemical reactions produce two chemical compounds: Calcium Silicate Hydrate (CSH), which is the strength producing crystallization, and Calcium Hydroxide (CH), a by-product also called free lime which is responsible for nothing much

To see BriteFume's technical data sheet, click on the following link: BriteFume Technical Data Why Silica Fume? Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2). High Quality Silica Fume Concrete Used in Cement-based Concrete Mortar and Refractory Castable . Product Description: Silica Fume Concrete collected and packed from silicon metal or ferrosilicon factories directly, the automatic and integrated production process guarantees the consistent quality. Silica fume originates from the oxidation of SiO gas produced in the processing of zircon sands, silicon sands, and ferrosilicon alloys in electric furnaces. The SiO2 formed is condensed into spherical particles and recovered in bag house filters. Silica fume is a mineral admixture, composed of submicron particles (100 to 150 times smaller than a grain of cement) of amorphous silicon dioxide.
