Sažetak
Ordinary Portland Cement (OPC) is currently the predominant building material in the construction industry, which heavily affecs the environment in series of ways. It would be great to replace OPC with a cheap and reliable material with less pronounced environmental impact. Hence, geopolymers are nowadays considered as the third generation of cements due to their sustainability. Specifically, a much lower CO2 footprint is presented which significantly benefits mitigation of environmental issues. In this work, we focused on chemical and (micro)structural changes that occur during the curing of (pre)mullite-based geopolymers. The influence of various factors was tested, such as the type of ions present in the activation solution and presence of additives for acgieveing desired properties of the composite. Moreover, samples were prepared in bulk and thin- film configuration which were further characterized by DTA-TGA, XRD, SEM, solid state NMR and SS-IS. Particular attention was devoted to improving conductivity by adding various conductive polymers to the geopolymer matrix. Obtained results enabled a better understanding of the patway towards desired properties. A challenging shift from relatively porous bulk to thin-films is presented, broadening the applicability of geopolymers to vertically mounted solar-cells.
