GURU CORPORATION is the Gujarat's largest manufacturer and supplier of silica fume. It is a key ingredient in advanced low, ultra-low and cement-free castables. It is highly reactive during sintering which leads to improved ceramic bonding at reduced firing temperatures. This material is also utilised in mortars, gunning mixes, shotcrete in tunnels, etc.
Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys. It primarily consists of amorphous (non-crystalline) silicon dioxide (SiO2). The individual particles are extremely small, approximately 1/100th the size of an average cement particle. One of the most beneficial uses of this material is in concrete. Because of its chemical and physical properties, it is a very reactive pozzolan. Concrete containing silica fume can have very high strength and can be very durable. It is available from suppliers of concrete admixtures and when specified, is simply added during concrete production. Placing, finishing, and curing silica fume concrete require special attention on the part of the concrete contractor.
