Abstract text:
Gypsum board is a widespread fire barrier used in house and general building construction. Gypsum board partitions and ceiling membranes are possibly the most common fire resistant construction approach employed in an extensive range of building types. The utilization of gypsum board as prime fire protection of light-flame wood or steel construction is ubiquitous. Gypsum board based systems are among those now broadly used, as walls or ceilings and it is principally employed as lining material in light-weight construction, which is a competent and cost effective technique of providing flexible partitioning assemblies in commercial and residential buildings. The thickness of the gypsum board lining and the configuration of the framing can be flexibly changed to meet specified fire performance requirements. The use of such systems is increasing every day and there demands to be more research on their properties and behaviour. This paper presents the properties of gypsum board which include the assemblies and standard fire tests and the thermal properties of gypsum in general and includes suggested properties of gypsum by different researchers.
Key Words:
