- 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.
- The silica
fume market in India is poised to grow by USD 10.83 billion during
2020-2024, progressing at a CAGR of over 5%
