| Abstract | Concrete has contributed to the development of modern architectural culture, but the cement as an adhesive agent for concrete produces large amounts of carbon dioxide emissions into the air during the manufacturing process. This study researches the practical use of structure, through the verification of structural stability, for geopolymer concrete. This is part of the development of core technology for greenhouse gas emission reduction by reducing energy consumption in construction, an industry that occupies 25% of the total energy consumption in South Korea. According to the experimental results of chemical reaction (i.e., acid reaction, sulfate resistance reaction and corrosion caused by sodium chloride) of fly ash-based geopolymer concrete, the theory and SEM analysis demonstrated that geopolymer concrete was acid resistant, sulfate resistant, and resistant to corrosion caused by sodium chloride. The basic properties were understood through qualitative analysis of a geopolymer concrete specimen using SEM, and through a study on the practical use of structure by verifying structural stability for geopolymer concrete, as part of development of technology. After future experiments and tests, the best geopolymer concrete ratio and curing method will provide a guideline. |
