Abstract

Lagani betoni su inovativni materijal sa dugom povijesti, čiji razvoj još i danas traje. Ovaj rad prikazuje karakteristike laganih betona da bi znali kada ga je efikasno primijeniti. Prednosti laganih betona su smanjene težine, poboljšanih izolacijskih svojstava i
povećane otpornosti na požar, ali te prednosti dolaze i sa svojim nedostacima poput smanjene čvrstoće i modula elastičnosti. Prikazane su vrste laganih betona ( ćelijasti, lakoagregatni i jednakozrnati ) te su objašnjenje prednosti i nedostatci svake vrste.
Također su prikazani najčešći agregati koji se koriste za proizvodnju. Objašnjena je specifičnost proizvodnje laganih betona kao i postojeće formule koje se mogu koristiti za početno doziranje smjese. Također pogledali smo kako različiti standardi definiraju i reguliraju uporabu laganih betona, te smo spomenuli i neke nedostatke postojećih standarda. Za kraj smo prikazali par primjera zgrada gdje se lagani beton primjenjivao

Abstract (english)

Lightweight concrete is an innovative material with rich historical background, whose development continues today. This paper aims to review characteristics of lightweight concrete so we could discern its optimal applications. Advantages of lightweight concrete is its reduced weight, increased insulating properties and increased fire resistance. There are different types of lightweight concrete (lightweight aggregate concrete, cellular concrete, and no fines concrete), each type exhibits distinctive production methods, as well as distinct advantages and disadvantages. Lightweight concrete also has a specific way of production, which differs from normal concrete, so we mentioned formulas which can be used for initial dosing of the mixture. This paper also sheds light on how different standards define and govern usage of lightweight concrete. Some limitations of standards are also mentioned. Finally, several exemplary architectural structures employing lightweight concrete as a building material are showcased within this study.
