Abstract

Diplomsko delo zajema pregled strokovne literature in ugotovitve dosedanjih izsledkov o konceptu biobetona. Beton je nepogrešljiv material na številnih področjih, velika pomanjkljivost pa je njegova nagnjenost k tvorjenju razpok, ki lahko nastanejo v svežem ali že strjenem betonu. Z biobetonom bi to pomanjkljivost odpravili, saj gre za beton, ki ima zmožnost samoceljenja. Biobeton je beton, v katerega se v fazi priprave doda reagent za samopopravljivost, sestavljen iz bakterij in organskih hranil. Trenutno se mnenja raziskovalcev še razlikujejo glede na to, katera vrsta bakterij in organskih hranil je najučinkovitejša ter kateri način vgradnje v betonsko sestavo je najboljši. Kljub temu pa vsi stremijo k enakemu cilju, in sicer narediti beton trdnejši in trajnejši, saj reagent za samopopravljivost vpliva tudi na njegove lastnosti. S pregledom dotične teme, nudi ta naloga podlago za nadalje študije na temo biobetona.

Secondary title: Bioconcrete
Secondary abstract: B.Sc. degree paper includes a literature review regarding state of the art concept of bioconcrete. Concrete plays an indispensable role in many fields, but it has a high tendency to form cracks in fresh or hardened state. Bioconcrete would eliminate this disadvantage, since it has the ability of self-heling. Bioconcrete is a concrete into which healing agent, consisting of bacteria and organic nutrients, is added during the preparation process. In the literature, researchers’ opinions differ which type of bacteria and organic nutrients are the most effective and which embedment in concrete matrix is the best. However, they all strive to make the concrete more solid and durable, since the healing agent also affects concrete’s mechanical properties. By reviewing this topic, the thesis provides the basis for further studies on the subject of bioconcrete.
