| Abstract | Until recent years fire resistant assemblies evolved more through practice than conscious development, They generally comprised well known materials such as plaster, brick and concrete, long recognizedfor their fire enduring qualities. Fire research, however, has resulted in the development of performance requirements for fire resistance and information on how these can be effectively and economically achieved.This has been in response to increased building volume and the availability of new building materials. Today, development of products and systems is often aimed at specklic building markets for which the fire resistance requirements are well defined. |
