Self Compacting Lightweight Concrete with Addition of Minced Brick : Undergraduate Thesis

Laki betoni imaju manju gustoću u odnosu na normalni beton. Smanjenje gustoće postiže se stvaranjem međuprostora između zrna krupnog agregata, stvaranjem pora u mortu ili upotrebom agregata sa 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 mješavine samozbijajućeg lakog agregata s dodatkom mljevene opeke. Prikazani su i analizirani rezultati ispitivanja u svježem i očvrslom stanju.Lightweight concrete has lower densitiy compared to normal concrete. Reducing desity is achieved by creating a space between the grains of course aggregate, creating voids in mortar or using the aggregates with larger content of pores. Lightweight aggregate concrete with expanded clay or slug, and aggregate of natural origin, achieve maximum strenght. In the experimental part of study, 2 different mixture of self compacting lightweight concrete have been made. Results obtained by testing properties of fresh and hardened concrete are presented and analysed
