Abstract

The investigations in the field of geopolymer binders indicated that this new material has a great potential to be an alternative to cement to reduce the carbon dioxide emissions. On the other hand, it was found that the traditional geopolymer has multiple defects, including the presence of viscous corrosive solutions. Researchers were interested in solving this problem and the traditional type was developed into one-part geopolymer and the need for solutions became in its composition and it became possible for this material to be an alternative to cement. But until now there are unexplained issues about one part geopolymers. In this instance, this study aims towards the investigated the fresh and hardened properties of one-part geopolymer mortar versus two-part geopolymer mortar and PC. The fresh and hardened properties that include workability, compressive strength, sulfate resistance, acid resistance and heat resistance were studied for samples cured at 30 OC and compared to PC samples cured by immersing in water. Moreover scanning electron microscopy (SEM) was investigated to support the test results. The results showed that, workability of one-part geopolymer mortar was enhanced by adding fly ash (FA). Moreover, the results revealed that higher compressive strength was achieved by adding ground granulated blast furnace slag (GGBS) and one-part geopolymer mortar exhibited superior resistance to sulfate, acid and heat by compared to PC. According to a SEM test one-part geopolymer mixes including GGBS were found to be more homogenous and dense than those containing FA
