Gypsum Plaster : Advantages and Disadvantages
When dry POP powder is mixed with water it hardens. This material which can be applied over brick, block or concrete surface to form a smooth surface is called gypsum plaster. Earlier, a 6 mm coat of gypsum plaster (termed as POP punning) is usually applied on the top of cement plaster to give a smooth finish to it before painting.

Aluminium powder is used at a rate of %–% by volume (depending on the prespecified density). When AAC is mixed and cast in forms several chemical reactions take place that gives AAC its light weight property (25% of the weight of concrete) and thermal properties. Aluminium powder reacts with calcium hydroxide and water to form hydrogen.
