Description
Microsilica, also
known as Silica Fume, collected during production of silicon metal
or ferrosilicon, is an
ultrafine powder with high SiO2 content and high pozzolanic
activity. It is used as a property-enhancing
material in many areas, such as concrete construction, refractory,
and chemical fertilizer.
Winitoor
microsilica complies with ASTM C ***0 standard. The recycle,
densifying and filling
processes are
automatically integrated in a closed environment without any
mixture or impurities.
We can fix
clients orders in a stable production base so as to ensure the
consistency and stability of quality.
Microsilica
(Silica Fume) is light grey to dark grey in color, and is available
in several
grades and
packaging options.

uAdvantages
1.Higher
compressive strength by ****0
2.Reduces the
rate of carbonation
3.Lower
permeability - Resistance to penetration of water, chloride &
other chemicals
4.Lower free lime
formation - Delays Ettringite and Thaumasite
formation
5.Controls
bleeding in fresh concrete
6.Lower Heat of
Hydration, which prevents formation of
cracks.
