Article Betonda Atık Vermikülit Kullanımının Betonun Mineralojik ve Kimyasal Yapısına Olan Etkisinin İncelenmesi(Gumushane University, 2022) Karakaya Harmanci, F.N.; Soğancioğlu Kalem, M.Today, new approaches are emerging regarding the recycling of waste materials and their use in building materials. With the reuse of these wastes, important environmental problems are avoided and the raw materials to be used in the production of building materials are also saved. From this point of view, within the scope of this study, it is aimed to evaluate the waste vermiculite mine, which is an important environmental problem and has not yet found an evaluation area, instead of aggregate in the concrete. In this context, the characterization of waste vermiculite (AVK) replaced with fine aggregate and the chemical and mineralogical compositions of the obtained concrete samples were revealed by SEMEDS, FTIR and XRD analyzes, and the chemical and mineralogical changes in the structure of the concrete were associated with the compressive strength of the concrete. According to the results obtained, the decrease in the compressive strength of the concrete with the increase of the waste vermiculite dose and the bound functional O-H groups seen in the chemical structure of the concrete show that the concrete mixture needs extra water. However, as a result of the obtained results, it has been shown that concrete containing low doses of waste vermiculite can be used in structural areas where the compressive strength is not important. © 2022, Gumushane University.
