Foundry
Microsilica (silica fume) is a by-product of silicon metal or ferrosilicon industries, is an amorphous silicon dioxide SiO2. This product reacts chemically with the calcium hydroxide in the cement paste which yields a calcium silicate hydrate gel that significantly enhances strength and durability. The super fine microsilica fills the voids between cement particles creating a very dense, less permeable concrete.

Application & Benefits of Microsilica (Silica fume):
In concrete:
The micro silica fume powder can be well filled in the cement particle space and make the slurry denser, mainly in the following:
Increase strength
Increase the density
Frost resistance
Early strength
Anti abrasion and anti-cavitation resistance
In Refractories:
Microsilica powder is widely used in the refractory industry. It has an important effect on the improvement of the amorphous refractory.
The production of amorphous and shaped refractory products as additives makes the strength and high temperature performance greatly improved.
Other Application:
Elastomers/Polymers
Silica sand is a primary component in the manufacturing of glass. It is a very
important raw material for standard and special glasses. The chemical purity of
silica sand is the principal determinant of strength, colour and clarity.
It is used to produce flat glass for building and automotive uses and for container glass that stores food and beverages. It reinforces glass fibres and required for the production of fibreglass insulation. It is applied in speciality glasses that include test tubes, scientific tools, television and CRT monitors, and also in incandescent and fluorescent lamps.
Calcium silicate bricks
For manufacturing calcium silicate bricks, silica sand is mixed with high calcium
lime with a sand to lime ratio of 10 or 20. These bricks contain good regularity,
smooth faces, and sharp corners with a wide variety of strength. The durability of calcium silicate bricks is similar to concrete and is not resistant to sulphur containing environments.
Silica sand for water filtration
Silica sand is an effetive filtration bed in the removal of contaminants in both
processing of wastewater and in the filtration of the drinking water. Silica sand
neutralizes the acidic elements to maintain optimal pH balance in water filters.
As it is chemically inert, it will not react when exposed to acids, contaminants,
volatile organics or solvents.
Metal Casting & Production
Silica sand is an essential part of the production of steel, ferrous and nonferrous foundry industries for de-oxidation and grain refinement. For obtaining desired internal or external shapes, metal parts are cast in silica sand. It is a preferred choice for castings that involve cast iron, steel, titanium and also used to clean the casting surfaces.
Paints & Coatings
Silica sand constitutes of high-performance properties such as brightness,
reflectance, oil absorption and colour-consistency. These properties help to
improve the overall appearance and durability of industrial and architectural
paints and coatings. Its low oil absorption nature improves finishing colour that makes a durable coating rich in pigments. Silica fillers improvement retention and also provide resistance to dirt, mildew, weathering and cracking
