The amount of CO2 released during cement production is near to 7% of total global production. CO2 is one such Green House Gas (GHG) responsible to have an impact on Climate Change. To lower this impact, ‘Cement-less’ concrete also known as ‘Geopolymer Concrete’ has been prepared. In the present study, different variables, i.e. (1) different Alkaline to Binder (AL/B) ratio, (2) type of curing regime and (3) different binder content (Fly Ash: GGBS) ratios were investigated. Effect of these on various Mechanical and Durability properties of Geopolymer concrete (GPC) has been studied. The curing temperature for oven cured specimens was kept constant at 60℃ and curing time as 24 h. Microstructural behaviour of GPC in terms of Scanning Electron Microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDS) was also conducted. Findings indicate improved Mechanical properties at a binder ratio of FA:GGBS ratio as 50:50. Additionally, a better strength at Alkaline to Binder ratio (AL/B) 0.45 was observed.

摘要

The amount of CO2 released during cement production is near to 7% of total global production. CO2 is one such Green House Gas (GHG) responsible to have an impact on Climate Change. To lower this impact, ‘Cement-less’ concrete also known as ‘Geopolymer Concrete’ has been prepared. In the present study, different variables, i.e. (1) different Alkaline to Binder (AL/B) ratio, (2) type of curing regime and (3) different binder content (Fly Ash: GGBS) ratios were investigated. Effect of these on various Mechanical and Durability properties of Geopolymer concrete (GPC) has been studied. The curing temperature for oven cured specimens was kept constant at 60℃ and curing time as 24 h. Microstructural behaviour of GPC in terms of Scanning Electron Microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDS) was also conducted. Findings indicate improved Mechanical properties at a binder ratio of FA:GGBS ratio as 50:50. Additionally, a better strength at Alkaline to Binder ratio (AL/B) 0.45 was observed.
