Although considerable research has been conducted on alkali-activated fly ash cementitious materials for geopolymer concrete production, few of which concentrated on the slag-based geopolymer concrete. This paper presents the results of an experimental investigation on the 7-day & 28-day compressive strength, as well as 28-day flexural strength of the wet mixed geopolymer concrete based on CDG and slag cementitious materials cured at ambient temperature. A total of 90 specimens were tested. The cementitious materials content, sand ratio, as well as the liquid-solid ratio were selected as the main parameters. Besides, the new alkali activator system was adopted to prepare the geopolymer. Effects of these variables on the compressive and flexural behavior of the wet mixed geopolymer concrete are plotted throughout this paper.
