Abstract:	V magistrskem delu je na podlagi pregledanih člankov in laboratorijskih preiskav predstavljena raziskava konoplje, konopljinega betona, izdelanih receptur apnenega konopljinega betona in materialov, ki ga sestavljajo. Raziskali smo fizikalne, mehanske in trajnostne lastnosti konopljinega betona in pripravljenih receptur apnenih konopljinih betonov z dodatki granulirane plavžne žlindre in portlandskega cementa 42,5 N, z vsebnostjo 5 % mase konopljinega pezdirja namesto agregata (zrnavosti 0/4 mm). Ugotovili smo, da na lastnosti konopljinega betona v otrdelem stanju vplivajo obdelava in sorta industrijske konoplje ter vrste uporabljenih veziv. Na otrdelih pripravljenih vzorcih smo opravili preiskave tlačnih in upogibnih nateznih trdnosti, od katerih so v obeh primerih najboljše rezultate dali vzorci z dodatkom portlandskega cementa in najslabše tisti z dodatkom mlete granulirane plavžne žlindre. Preverjali smo protimikrobno učinkovitost pripravljenih vzorcev v otrdelem stanju, kjer sta cono inhibicije razvila vzorca z dodatkom deleža cementa in dodatkom cementa skupaj z žlindro v vezivu. Od pripravljenih receptur je TGA/DSC pokazala, da ima največji masni delež CaCO3 in najmanjši masni delež Ca(OH)2 vzorec z dodatkom cementa. Ugotovili smo, da so cene konopljinih betonov v Evropi redko dostopne, močno variirajo zaradi različnih sestav in načina vgrajevanja in so posledično težko primerljive. Primerjava raziskav LCA pri različnih parametrih je dokazala, da je konopljin beton, sestavljen iz konopljinega pezdirja, veziva in vode, v svojem življenjskem ciklu ogljično negativen. Konopljin beton, ki ne vsebuje kamnitega agregata, je primeren za uporabo v Sloveniji, saj obstaja iz njega že več zgrajenih objektov, kot tudi podjetje, ki se ukvarja z gradnjo s konopljinim betonom.

Title:	Economic, construction and life cycle analysis of hempcrete application in Slovenia
Abstract:	Based on reviewed articles and laboratory experiments, the master’s thesis presents research on hemp, hempcrete, prepared lime hemp concrete mixtures and the materials that form it. We investigated the physical, mechanical and sustainable properties of hempcrete and ready-made lime hemp concrete mixtures with the addition of granulated blast furnace slag and Portland cement 42.5 N, where 5 % in mass of aggregate (grain size 0/4 mm) was replaced with hemp hurds. We found that the properties of hemp concrete in the hardened state are influenced by the processing and variety of hemp and the type of binder used. We performed compressive and bending tensile strength tests on the hardened prepared samples, of which the best results were obtained in both cases by samples with the addition of Portland cement and the worst by those with the addition of ground granulated blast furnace slag. We checked the antimicrobial effectiveness of the prepared samples in hardened state, where the zone of inhibition was developed by the samples, which contained a proportion of cement and cement with slag in the binder. From the prepared mixtures TGA/DSC showed that the sample with the addition of cement has the largest mass fraction of CaCO3 and the smallest mass fraction of Ca(OH)2. We found that the prices of hemp concrete in Europe are rarely available, they vary greatly due to different compositions and methods of construction, and are consequently difficult to compare. A comparison of LCA research with different parameters proved, that hemp concrete, made from hemp hurds, binder and water is carbon negative in its life cycle. Hemp concrete, which does not contain stone aggregate, is suitable for use in Slovenia, as there are already several buildings built from it, as well as a company, engaged in construction with hemp concrete.
