ABSTRACT: This study investigates the effect of various alkali-modulus ratios and dosages of alkali-
activators on the setting time and compressive strength for Alkali-Activated Fly Ash (AAFS) mortars.
Experimental results show that the alkali-modulus ratio has a significant influencing on pH value. The
lower the alkali-modulus ratio is, the higher the pH value is. However, no obvious ...
