GYPSUM BOARD & GYPSUM WALL PUTTY
[CODE NO. 3713]
Gypsum Plaster Boards are constructional sheets composed of concined Gypsum with about 15% fibre. Its outstanding contributes are fire resistance, dimensional stability, easy workability and low cost fibres are added to provide crack resistance and for fire resistance water repellent chemicals may be added to the board core.
The various sources of gypsum in India when developed will yield in addition to high grade gypsum. According to the present knowledge the latter has prospect of economic use as building materials, namely plaster, plaster boards and block. Gypsum plaster boards can be used as covering for walls ceilings and partition in normally by environments and under controlled conditions of humidity and temperature in buildings.
Gypsum plaster boards are selected for use according to their type, size, thickeners and edge profit. The Boards may be used for example to provided dry lining finishes to masonry walls, to ceilings, to steel or timber framed partitions, or as claddings to structural steel columns and beams, or in the manufacture of pre-fabricated partition panels.
The boards may be fixed by nailing, screwing, or sticking with gypsum based or other adhesives. They may also be inserted in lay-in grids and/or secured by clips.
The manufacture of gypsum wall board originated in vision the early 1800's and has science spread to all highly industrialized Engineers of the work. The earliest Gypsum Board was known to the trade as plaster boards because it was intended or use as a base for plastering. In the 1820's gypsum board in large sheets and with an improved surface finish was brought to market, permitting direct application of decorative finishes without plastering.
