Abstract

Razvojem tehnologije i povećanjem zahtjeva za sigurnošću u današnje doba graditeljstva potrebno je adekvatno zaštititi građevine od požara i vatre. U modernoj gradnji prisutni su novi materijali organskog i anorganskog podrijetla, stoga je potrebno posvetiti posebnu pažnju protupožarnoj zaštiti u cilju očuvanja materijalne imovine i ljudskih života. Primjena protupožarnih sustava zaštite nudi očuvanje svojstava materijala te omogućava stabilnost konstrukcija izloženih požaru i povišenim temperaturama. Time se dobiva dragocjeno vrijeme za evakuaciju i spašavanje ljudskih života i produžuje se kratki period za djelovanje vatrogasnih službi. Protupožarni sustavi zaštite od požara dijele se na aktivne i pasivne sustave zaštite. Za najbolje rezultate preporučuje se neka od kombinacija i aktivnih i pasivnih sustava protupožarne zaštite. U ovom radu detaljnije je proučavana pasivna zaštita od požara, posebice protupožarna zaštita čelika ekspandirajućim premazima. Opći konstrukcijski čelik najzastupljeniji je materijal u graditeljstvu zbog dobrih mehaničkih svojstava i ekonomičnosti, ali pri izloženosti visokim temperaturama drastično gubi svoja mehanička svojstva što može dovesti do urušavanja građevina prilikom požara. Cilj rada bio je ispitati svojstva vatrootpornosti ekspandirajućeg protupožarnog premaza na nelegiranom čeliku pri izloženosti različitim vremenskim uvjetima.

Abstract (english)

With the development of technology and the increase of safety requirements in the modern construction era, it is necessary to adequately protect buildings from fire. In modern construction, new materials of organic and inorganic origin are present, so it is necessary to pay special attention to fire protection to protect property and human life. The application of fire protection systems provides the preservation of material properties and enables the stability of structures exposed to fire and elevated temperatures. This buys valuable time for evacuation and saving lives and extends the short period of time for firefighters to respond. Fire protection systems are divided into active and passive protection systems. To achieve the best results, a combination of active and passive fire protection systems is recommended. In this paper, passive fire protection (especially fire protection of steel with intumescent coatings) is studied in detail. Steel is the most used material in construction due to its good mechanical properties and economy. However, when exposed to high temperatures, it drastically loses its desirable mechanical properties, which can lead to the collapse of buildings during a fire. The aim of this study was to investigate the fire-protective properties of the intumescent fireproof coating on mild steel when exposed to different weather conditions.
