Abstract

U ovom završnom radu provedeno je eksperimentalno ispitivanje volumenskih deformacija mortova s pepelom drvne biomase koji nastaje izgaranjem u energanama. Ispitano mješavina; jedna bez dodatka pepela (referentna) te četiri s različitim udjelima pepela (20 i 30 %). U teorijskom dijelu opisane su volumenske deformacije kao i primjena drvne biomase u cementnim kompozitima, dok je u sklopu eksperimentalnog dijela provedeno ispitivanje skupljanja uslijed sušenja i dugotrajnog autogenog skupljanja mortova pepelom drvne biomase kao zamjene dijela cementa. Također, ispitana su i svojstva u svježem stanju, tlačna i čvrstoća na savijanje te je provedena analiza dobivenih rezultata ispitivanja.

Abstract (english)

An experimental examination of voluminous deformations of mortars from wood ash, which occurs by combustion in powerplants, is conducted in this bachelor thesis. compositions are examined; one without the addition of ash (reference measurement), four others with different percentage of ash (10, 15, 20 and 30%). In the theoretical section the paper, voluminous deformations, as well as the application of the wood biomass ash cement composites are described, while the experimental examination displayed shrinkage and a long-term autogenous shrinkage of mortars with wood biomass substitute for a portion of cement. In addition, properties in fresh state, compressive strength, and flexural strength are examined, and an analysis of the examination results has been
