Experimental investigation of the effects of temperature on the morphological characteristics of geopolymer binders

Abstract Since the beginning of this century, assessment environmental impacts and global warming potential industrial practices technologies are on top agenda. Therefore, many construction materials such as cement systems being designed for reducing greenhouse gas emissions. For that purpose, petroleum industry is also striving developing environmentally friendly cementing oil well application; example, a better alternative to class-G cement, which consumed in tremendous amount worldwide. In finding greener geopolymer binders researched possible applications oil-well jobs. This paper presents experimental investigation effects temperature morphological characteristics binders. sodium silicate hydroxide were used alkaline activator with fly ash precursor. Fifteen samples prepared density 10, 11, 13, 15 17 ppg (3 each value density). The subjected 30, 60, 90 °C cured water bath 24 h. Morphological microstructural analyzed using XRD FESEM. an overview, increases significantly impact geopolymerization process where microstructure produces more reacted particles, results excellent mechanical strength. Generally, strength geopolymers associated dissolution FESEM image mixture at clearly shows it underwent extensive formation continuous alumino-silicate gel almost entirely resulting relatively dense matrix.
