The construction industry is a significant contributor to global carbon dioxide (CO2) emissions and only cement industry contributes about eight percentage of global carbon dioxide emissions, exacerbating the challenges of climate change. To address this issue, research has focused on environmentally friendly concrete solutions that can mitigate CO2 emissions during production and use. One area of investigation is the utilization of zeolite in concrete, which has shown promise in reducing CO2 emissions. Zeolite, with its unique crystalline structure, could capture CO2 from the atmosphere. By analyzing the compressive strength of concrete mixed with different zeolite ratios, as well as conducting Scanning Electron Microscope (SEM) analysis to examine the microstructure of the CO2 captured concrete surface. CO2 test was conducted in a glass observation chamber using CO2 gas cylinders and gas analyzer. Maximum CO2 reduction was observed about 25%. This study demonstrates that incorporating zeolite can enhance both the compressive strength and CO2 reduction capacity of the concrete. From the visual inspection of SEM images, a noticeable difference has been observed between the surface microstructure of conventional concrete and zeolite-based concrete.
