Abstract
U radu je temeljem pregleda dostupne literature provedena analiza utjecaja mineralnih dodataka na mehanička svojstva betona na sobnim i visokim temperaturama. Mineralni dodaci se koriste kao zamjena za dio Portland cementa ili agregata kako bi se poboljšala svojstva u svježem i očvrsnulom betonu te smanjila emisija ugljičnog dioksida koja nastaje pri proizvodnji Portland cementa. Ovim radom obuhvaćena su fizikalna i kemijska svojstva te utjecaji dodatka letećeg pepela, granulirane zgure, silicijske prašine i metakaolina na mehanička svojstva betona. Analizirana mehanička svojstva su: tlačna čvrstoća, vlačna čvrstoća i modul elastičnosti. Analiza dostupnih istraživanja je pokazala da se mehanička svojstva betona izloženog visokim požarnim temperaturama u pravilu smanjuju, međutim mineralni dodaci utječu na formiranje različite mikrostrukture u betonu koja različito utječe na preostala svojstva.
Abstract (english)
Based on a review of the available literature, the paper analyzes the influence of mineral additives on the mechanical properties of concrete at room and high temperatures. Mineral additives are used as a substitute for a portion of Portland cement or aggregates to improve properties in fresh and hardened concrete and reduce carbon dioxide emissions from Portland cement production. This work analyses the physical and chemical properties and the effects of the addition of fly ash, slag, silica fiume and metakaolin on the mechanical properties of concrete. The analyzed mechanical properties are: compressive and tensile strength and modulus of elasticity. The analysis of available research has shown that the mechanical properties of concrete exposed to high fire temperatures generally decrease, however, mineral additives affect the formation of different microstructure in concrete, which can differently affect the residual properties.
