Abstract

Alkali-activated binders (AABs) have garnered significant interest as promising materials for construction and repair purposes ever since their discovery. They have proven to be environmentally advantageous, causing less pollution compared to conventional cement. These compelling features have made AABs a compelling choice in the realm of construction and repair, offering a sustainable alternative with superior performance. This paper aims to investigate the effect of activator concentration (Sodium hydroxide, NaOH) on AAB composed of electric arc furnace slag (EAFS) and class F fly ash (FA). The study involved a comprehensive analysis conducted over a 28-day curing period at room temperature, utilizing techniques such as X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TG-DTA) to gain a thorough understanding of the developed binders. The results of the study revealed the formation of hydrated phases in the AAB samples. The detected hydrated phases suggest that the activator concentration (NaOH) has a significant impact on the hydration process of AABs.
