By using cement in concrete buildings, significantly heat and CO

are produced, thereby contributing to global warming and climate change. To find a feasible way to reduce its environmental impact, this study aims to evaluate zeolite powder as a partial replacement and reduce graphene oxides as an additive to minimize carbon dioxide in concrete. Zeolites were added in three different quantities (5%, 10% and 15%) to concrete mixtures, and reduced graphite oxides were added in three different quantities (0.03%, 0.05% and 0.07%). The aim of this study is to evaluate the effectiveness of these additives in reducing carbon dioxide emissions during cement manufacturing. The study proposes the creation of more ecologically responsible and sustainable construction materials by adding zeolite and reduced graphene oxides can significantly reduce carbon dioxide emissions in concrete, with 5% and 0.07% being the optimal proportions for each additive in mechanical and microstructural analysis like SEM, EDX and Raman spectroscopy test. The load and deflection behaviour under flexural behaviour CC, ZE, rGO and ZE + rGO were identified, and the load and deflection graphs under flexural behaviour CC, ZE, rGO and ZE + rGO were measured with RC beams.
