Structural, Mechanical and Chemical Properties of Low Content Carbon Geopolymer

In recent years geopolymers have shown increased interest as binders with low CO2 emission compared to Portland cement. The main goal of this research is focused on connecting green and sustainable characteristics the mechanical chemical properties fly ash-based geopolymer. samples different ratios ash (FA) metakaolin (MK) were prepared. X-ray powder diffraction (XRD) showed that in geopolymer synthesis reaction a new amorphous phase was formed. Diffuse reflectance infrared Fourier transform spectroscopy (DRIFT) confirmed characteristic bands Si-O O-Si-O groups at 1045 cm?1. Compressive strength analysis revealed optimal ratio FA MK 50:50 exhibits highest value. photoelectron (XPS) total reduction carbon content alkali-activated stoichiometry 50:50. This indicates possibility obtaining material an almost complete absence carbon, which implies further application very high environmental potential zero emissions.
