Abstract
Laki beton ima manju gustoću u odnosu na normalan beton. Smanjenje gustoće postiže se stvaranjem međuprostora između zrna krupnog agregata, stvaranjem pora u mortu ili upotrebom agregata s velikim sadržajem pora. Najveće čvrstoće postižu lakoagregatni betoni s agregatom od ekspandirane pečene gline ili zgure, te s agregatom prirodnog porijekla. U eksperimentalnom dijelu rada napravljene su 2 različite vrste betonskih mješavina. Prikazani su i analizirani rezultati ispitivanja lakog samozbijajućeg betona s dodatkom mljevene opeke u svježem i očvrslom stanju.Lightweight concrete has a lower density compared to normal concrete. Reducing density is achived by creating a space between the grains of coarse aggregate, creating voids in the mortar or using the aggregates with a large content of pores. Lightweight aggregate concrete with expanded clay or slag, and the aggregate of natural origin, achive maximum strength. In the experimental part of the work 2 different types of concrete mixes were made. Results obtained by testing properties of fresh and hardened lightweight self - compacting concrete with ground brick are presented and analysed
