Abstract
Rastuća proizvodnja otpada, koja je rezultat rasta stanovništva i industrije, dovodi do sve brojnijeg stvaranja odlagališta za taj otpad. Jedan od najčešćih prehrambenih otpadnih materijala je ljuska jajeta kod koje se već godinama bilježi porast potrošnje. Osim povećanja količine otpada, prisutna je i rastuća eksploatacija prirodnog agregata za građevinarstvo. S obzirom na kemijski sastav ljuske koji je vrlo sličan sastavu vapnenca, ljuska je pronašla moguću primjenu i u građevinarstvu kao zamjena za navedene prirodne materijale. U okviru ovog rada ispitana je mogućnost djelomične zamjene sitnog agregata ljuskom jajeta u mortovima i mikro betonima. Izrađene su mješavine morta i mikro betona s različitim udjelima ljuske jajeta te su ispitana njihova svojstva u svježem i očvrsnulom stanju. U svježem stanju izmjerene su konzistencija, gustoća te poroznost mješavina, dok su u očvrsnulom stanju ispitane tlačna čvrstoća te vlačna čvrstoća savijanjem. Provedena je analiza svih rezultata s ciljem utvrđivanja optimalne količine ljuske koja bi se mogla primijeniti u mješavinama morta i mikro betona, a da ujedno zadrži zadovoljavajuća svojstva u svježem i očvrsnulom stanju.
Abstract (english)
The growing production of waste, which is the result of the growth of the population and industry, leads to the creation of more and more landfills for that waste. One of the most common food waste materials is eggshell, the consumption of which has been increasing for years. In addition to the increase in the amount of waste, there is also a growing exploitation of natural aggregate for construction. Given the chemical composition of the eggshell, which is very similar to the composition of limestone, the shell has found a possible application in construction as a substitute for the aforementioned natural materials. Within the framework of this work, the possibility of partially replacing fine aggregate with eggshell in mortars and micro-concretes was examined. Mixtures of mortar and micro concrete with different proportions of eggshell were made and their properties were tested in the fresh and hardened state. In the fresh state, the consistency, density and porosity of the mixtures were measured, while in the hardened state, the compressive strength and tensile strength by bending were tested. An analysis of all the results was carried out with the aim of determining the optimal amount of shell that could be applied in mortar and micro concrete mixtures, while at the same time retaining satisfactory properties in the fresh and hardened state.
