Plaster of Paris, or simply plaster, is a type of
building material based on calcium sulfate hemihydrate, nominally
(CaSO4)2.H2O. It is created by heating gypsum to about 150°C. When the
dry plaster powder is mixed with water, it re-forms into gypsum, initially
as a paste but eventually hardening into a solid. The structure consists of
sheets of Ca2+ and SO42- ions held together by hydrogen bonds in the water
molecules. The grip between these sheets is easily broken, so plaster is
fairly soft. Plaster is used as a building material similar to mortar or
cement. Like those materials plaster starts as a dry powder that is mixed
with water to form a paste, which then hardens. Unlike those materials,
plaster remains quite soft after drying, and can be easily manipulated with
metal tools or even sandpaper.
Features of Balajee Plaster of Paris :
- It is manufactured by using high grade natural mineral gypsum &
highly abrasive & inert material blended together
- Natural oven backed highly abrasive SIO2 is used for high purity
- Due to presence of highly abrasive material, water absorption is low
- Surface & development strength is high & hence resistance
high..
- Water required during mixing is less. No patch mark can be observed
once it is set and dry.
- Specially formulated ready mix reinforced gypsum plaster, for regular
and flyash bricks applications provide excellent bonding, for any type
of smooth and rigid background directly.
- Density of the material is high, as compared to regular gypsum
plaster
- Smooth surface is achieved and hence the paint consumption is less.
- Specially formulated and designed plaster is produced for specific
requirement to give unmatched finish and brightness to the surface.
