Abstract

Lagani beton posebna je vrsta betona čija je volumenska masa smanjena u odnosu na obične betone. To smanjenje postiže se upotrebom laganog agregata porozne strukture koji doprinosi i dobroj toplinskoj vodljivosti, pa su lagani betoni dobri izolatori topline i zvuka. U radu je, temeljem dostupne literature, najprije obrađena povijest laganih betona, a zatim agregati koji se koriste za njihovu proizvodnju. Dana je podjela laganih betona prema namjeni te načinu proizvodnje. Opisana su mehanička i trajnosna svojstva te opisane konkretne primjene u visokogradnji, kod izrade mostova te za izradu specijalnih konstrukcija. Na kraju su dane mogućnosti uporabe prirodnih materijala za proizvodnju laganih betona kako bi se smanjio ekološki otisak.

Abstract (english)

Lightweight concrete is a special type of concrete whose volumetric mass is reduced compared to conventional concrete. This reduction is achieved by using lightweight aggregates with porous structure, which also contributes to good thermal conductivity of the final material. Therefore, lightweight concretes have good thermal and sound properties. The work, in accordance to avaliable literature, first describes the history of lightweight concrete, and then the aggregates used for their production. Then their classification according to intended use and production method is described. The mechanical and durability properties are listed, and specific applications in building construction, bridge building and the manufacture of special structures are described. Finally, the possibilities of using natural materials for the production of lightweight concrete are highlighted in order to reduce environmental footprint.
