- Silica fume is a
very fine pozzolanic material, composed of amorphous silica produced by
electric arc furnaces as a byproduct of the production of elemental
silicon or ferro silicon alloys.
- Silica fume, also
known as microsilica, is a byproduct of the reduction of high-purity
quartz with coal in electric furnaces in the production of silicon and
ferrosilicon alloys.
- Microsilica is a by
product of the manufacture of silicon and ferrosilicon alloys. It
consists of grey powder having extremely fine spherical particles of
amorphous silica (sio2).
- Silica fume, also
known as microsilica, is a byproduct of the reduction of high-purity
quartz with coke in electric arc furnaces in the production of silicon
and ferrosilicon alloys.
- Microsilica (MS) or,
as it often called, silica fume is a second-hand product in the
production of silicon metal (Si-met) and ferrosilicon (FeSi). The
production process of Si-met and FeSi is very polluting, and microsilica
was discovered during the process of how to avoid pollution.
- Microsilica has
proven to be an excellent admixture for Portland cement concrete.
Addition of microsilica to a concrete mix usually results in significant
improvements in strength, durability and permeability. Some of the
improvements to the concrete properties occur because microsilica is a
pozzolan. Pozzolans are finely divided silica that combine with free
lime (calcium hydroxide) to create more calcium silicate
hydrate.
- Microsilica is
estimated to be about a hundred times finer than cement, giving it the
ability to plug voids between cement particles, and helping it increase
the density of the cement matrix.
- Silica fume can be
used in a variety of cementitious products such as concrete, grouts, and
mortars as well as elastomer, polymer, refractory, ceramic and rubber
applications.
- Silica Fume is used
in concrete to improve its properties. It has been found that Silica
Fume improves compressive strength, bond strength, and abrasion
resistance; reduces permeability; and therefore helps in protecting
reinforcing steel from corrosion.
- Silica fume is a
by-product of producing silicon metal or ferrosilicon alloys in smelters
using electric arc furnaces. These metals are used in many industrial
applications to include aluminum and steel production, computer chip
fabrication, and production of silicones, which are widely used in
lubricants and sealants.
- The globalisation of
the Indian economy paved the way for easy availability of micro-silica
and latest superplasticisers in the country. M60 and higher grades of
concrete are now becoming popular in the country with its proven utility
in the construction of important structures.
- A major marketing
firm of microsilica in the country has estimated its turnover in the
current year be approximately seven to eight hundred
million
rupees.
- Most of the Indian
fly ashes contain calcium oxide less than 5 percent. With the facility
of RMC plants one can use large volumes of low calcium fly ashes with
small percentage addition of micro-silica to produce high early strength
and durable concretes.
- In global
competition within the metal industry and especially regarding
microsilica, there is a high demand for logistic efficiency. To move
microsilica from one side of the world to the other is a very
costly.
