Micro-silica fume, also called silica
fume or silicon powder. It is obtained by the unique design of the
collection of powdered and amorphous silica. The average diameter of the
particle is between 0.15 to 0.20μm and have the surface area between
15000 to 20000m2 / kg. It also has strong surface activity. For many
years, micro-silica fume is being widely used in metallurgy, chemical,
construction and other fields. A large amount of micro-silica fume is
added to concrete or cement mixture for improving their performance. Due
to this mixing, the mixture becomes anti freeze, non penetrative,
corrosion resistant, wear resistant and gets ultra high strength. Due to
all these benefits, this mixture is used for the construction of high
rise buildings, tunnels, runways of airports, highways, railway bridges,
port terminals, hydroelectric power plants and dams. Micro-silica fume
can also be utilized for the production of ceramic products and
refractories since it improves the durability and strength of the
product. It plays an important role in improving the performance of
materials, hence used as fillers in various polymer materials along with
rubber, resins, coatings and paints.
Micro-silica fume has many beneficial characteristics. Unlike cenosphere India, it improves the liquidity of casting refractory, reduces the consumption of water thereby making it simple to shape and greatly improves the efficiency. Because of its role as interstitial, strength and density of refractory have improved greatly.

In case of concrete, micro silica has many benefits. Unlike cenosphere
from India, significantly improves the performance of pumping and
strength of concrete. Since it makes the concrete waterproof, it is used
in the manufacture of chemical concrete, high rise buildings, tunnels
and the basement of the subways, tunnels. Since it has properties of
high density, it can prevent effectively the penetration of chloride and
sulfate ions on the concrete, thereby avoiding the subject to corrode
thus increasing the concrete life.
