Sažetak
Many studies have been directed to structural behaviour under fire conditions over the last decade. The results of these studies indicate that fire has different effects on construction materials and that concrete is the one that performances well at elevated temperatures. This good fire performance is mainly due to concrete's constituent materials (i. e. binder and aggregate) which make a material that is essentially inert up to certain temperatures and which has poor thermal conductivity. Since a lot of articles have already elaborated the special type of cement as a material that gives increased fire resistance to concrete, this paper will focus on the types of aggregates (vermiculite, perlite, expanded clay, slag) that improves its fire resistance. This paper presents properties of fire resistant aggregates mentioned above, as well as the results of preliminary testings (compressive strength, behaviour under fire conditions) of concrete made of them.
