Abstract

V sklopu diplomske naloge sem se ukvarjala z raziskavami mešanic za utrjevanja konstrukcijskih elementov historičnih stavb. V prvi vrsti je treba zadostiti kriterijem utrjevanja objektov za zagotavljanje mehanske odpornosti in stabilnosti stavbe. V drugi vrsti pa je treba stavbno dediščino ohraniti, z upoštevanjem konservatorsko-restavratorskih pristopov. To pomeni, da se originali ne odstranjujejo, temveč se vanje minimalno posega. Osredotočili smo se na uporabo belega Portlandskega cementa, s katerim smo želeli pripraviti čim bolj stabilno injekcijsko mešanico. Zasnovali smo več sestav apneno-cementnih injekcijskih mešanic, ki so vsebovale različne deleže cementa. Naš cilj je bila mešanica, ki je stabilna in vsebuje najmanjši možni delež cementa za doseganje mehanske odpornosti, hkrati pa je kompatibilna z ohranjenimi originalnimi materiali. Diplomska naloga najprej predstavi problematiko ohranjanja kulturne dediščine in razloge za njeno propadanje. V nadaljevanju so predstavljeni kriteriji za pripravo kvalitetne injekcijske mešanice. Sledi predstavitev injekcijskih mešanic ter rezultatov raziskav svežih in strjenih mešanic.

Secondary title: Influence of different cement types on the properties of lime-cement injection grouts
Secondary abstract: In the framework of the diploma thesis I studied structural injection grouts used to strengthen structural elements of historical buildings. First, we have to meet criteria regarding strengthening of the buildings, which assure their mechanical resistance and stability. Secondly, we have to preserve architectural heritage by taking into account the conservation and restoration approaches. This means that the originals are not removed, and new interventions are minimal. We focused on the use of white Portland cement, with which we aimed to prepare grout mixture with optimum stability. We designed several compositions of lime-cement grout mixtures, with different cement contents. Our goal was production of grout mixture with high enough stability at minimum cement content that assures adequate mechanical resistance of masonry wall and at the same time compatibility with original materials of the wall. The diploma thesis initially presents approaches to conservation of cultural heritage buildings and the reasons for the decay of materials and elements. In continuation, criteria for the preparation of injection grouts of adequate quality are presented. Finally, we present the composition of tested grout mixtures and their properties in fresh and hardened state.
