20.500.12556/RUL-172098 Moderni betoni v smeri zelenega prehoda Modern concretes towards the green transition Beton je najpogosteje uporabljen gradbeni material na svetu, vendar njegova proizvodnja predstavlja enega največjih virov emisij CO$_2$ na svetu. Zato je zmanjševanje emisij tega plina en izmed največjih izzivov današnje družbe. V tej diplomski nalogi so predstavljeni načini kako doseči ta cilj in kako te metode vplivajo na lastnosti betona. Sodobne strategije za zniževanje ogljičnega odtisa betona vključujejo zamenjavo klinkerja z mineralnimi dodatki (leteči pepel in mleta granulirana visokopečna žlindra), LC$^3$ cementi, uporaba alternativnih veziv (geopolimeri in MgO – cementi), postopki karbonatizacije, vgraditev recikliranih betonskih agregatov in implementiranje ocene življenskega cikla za celovito oceno vpliva posameznega pristopa na okolje. Concrete is the most widely used construction material in the world; however, its production represents one of the largest sources of CO$_2$ emissions globally. Therefore, reducing these emissions is one of the greatest challenges of modern society. This thesis presents different approaches to achieving this goal and examines how these methods affect the properties of concrete. Modern strategies for lowering the carbon footprint of concrete include the replacement of clinker with mineral additives (fly ash and ground granulated blast furnace slag), LC$^3$ cements, the use of alternative binders (geopolymers and MgO-based cements), carbonation processes, the incorporation of recycled concrete aggregates, and the implementation of life cycle assessment (LCA) for a comprehensive evaluation of the environmental impact of each approach.
