Mechanical Properties Investigation and Optimization of Ambiently Cured Alkali-Activated Concrete

Abstract

The mechanical, microstructural and statical interpretation of the Alkali Activated Concrete (AAC), prepared using fly ash with crushed granulated corex slag as the binder ingredient, are examined in this work. Here, cast in-situ alkali-activated concrete strengths and substitute slag concentrations of 0-50 % by fly-ash weight were undertaken to determine a workable manufacturing process and were all considered for up to 28 days. Moreover, in microstructural research, C-A-S-H gel is produced by adding Ground Granulated Corex Slag (GGCS) to the binder-generated structural changes in the in-situ alkali-activated concrete. As a result, this research obtained perfect mixture fractions by synthesizing 25 % GGCS with 0.4 % of the liquid-to-binder ratio, in addition, a unified desirability of 80 % was attained.
