Abstract

Osnovni cilj ovog diplomskog rada je eksperimentalno određivanje utjecaja različitih tipova ploča na bazi gipsa na ponašanje laganih kompozitnih panela pod utjecajem visokih požarnih temperatura. U prvom dijelu rada je provedena termogravimetrijska (TG) analiza četiri različite ploče do 1000 °C. Ispitane su dvije vrste gips-vlaknastih ploča različitog razreda reakcije na požar, gips-kartonska ploča te gips-kartonska ploča za vlažne prostorije. Rezultati su pokazali da je gubitak mase gotovo jednak za sve ispitane ploče do temperature od 300 °C, dok nakon spomenute temperature veći gubitak mase pokazuju obje vrste gips-vlaknastih ploča. Gubitak mase je povezan s endotermnim reakcijama u kojima se troši toplina što ih opravdava kao bolju opciju za zaštitu u uvjetima visokih temperatura. U drugom dijelu je ispitana otpornost na požar dva uzorka kompozitnih laganih panela koji su se sastojali od: čelične nosive konstrukcije, polimerne toplinske izolacije te po tri gips-vlaknaste ploče s obje strane panela. Konfiguracije su se razlikovale u vrsti gips-vlaknaste ploče na neizloženoj strani panela, a tijekom ispitivanja se pratio porast temperature kroz presjek panela. Razvijene temperature na neizloženoj strani panela ukazuju na isti razred otpornosti na požar u pogledu svojstva izolacije, bez obzira na korištenu vrstu ploče.

Abstract (english)

The main objective of this work is to experimentally determine the influence of different types of gypsum-based boards on the behavior of lightweight composite panels under the fire. In the first part of the work, a thermogravimetric (TG) analysis of four different boards up to 1000°C was performed. Two types of gypsum fiberboards, gypsum plasterboards and gypsum plasterboards for humid rooms were tested. The results showed that the mass loss is almost the same for all tested boards up to a temperature of 300 °C, while after the mentioned temperature a greater mass loss is observed for both types of gypsum fiberboards. The mass loss is associated with endothermic reactions that consume heat, which justifies them as a better option for protection at high temperatures. In the second part, the fire resistance of two specimens of lightweight composite panels was tested, consisting of a load-bearing steel structure, a polymer thermal insulation and three gypsum fiberboards on both sides of the panel. The configurations differed by the type of gypsum fiberboard on the unexposed side of the panel, and the temperature rise across the panel cross-section was monitored during the test. The temperatures that developed on the unexposed side of the board showed the same fire resistance rating in terms of insulation properties, regardless of the type of board used.
