A study on modulus of elasticity and Poissons ratio of GGBFS-metakaolin-based geopolymer concrete

Key Points

• This research aims to investigate the modulus of elasticity and Poisson's ratio of geopolymer concrete made with GGBFS and metakaolin.
• Analyzed the mechanical properties of GGBFS-metakaolin-based geopolymer concrete.
• Conducted tests to measure modulus of elasticity and Poisson's ratio.
• Evaluated different mixtures of GGBFS and metakaolin.
• Found increased modulus of elasticity with certain GGBFS-metakaolin ratios.
• Measured Poisson's ratio values consistent with traditional concrete materials.
• Noted improved mechanical performance in geopolymer concrete compared to conventional mixtures.
