Experimental study of thermo-chemical behaviour of gypsum based material under standard ISO 834 fire condition / Yannick Mélinge in European journal of environmental and civil engineering, Vol. 14 N° 5 (Mai 2010) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 14 N° 5 (Mai 2010) . - pp. 561-577 Titre : Experimental study of thermo-chemical behaviour of gypsum based material under standard ISO 834 fire condition Type de document : texte imprimé Auteurs : Yannick Mélinge, Auteur ; Khanh Son Nguyen, Auteur ; Christophe Lanos, Auteur Année de publication : 2011 Article en page(s) : pp. 561-577 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Mineral  material  with  large  latent  heat  Thermal  and  chemical  properties  Plaster  board  High  temperature Index. décimale : 624 Constructions du génie civil et du bâtiment. Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : described ( type plaster) under high temperature (ISO 834). Material temperature versus time and main space direction (1D description along the thickness) is presented and analysed. The temperature distribution in the cold convection zone is analysed too. The mass loss under temperature increase is then presented and the radiative thermal flux too. Such research work gives some particular data to improve the accuracy of a combined thermal-chemical numerical model used with large latent heat mineral material. Plaster boards are usually used for passive fire protection. The kinetic chemical conversion is also estimated and an evaluation of the thermal exchange coefficients on the cold face is proposed.
