The influence of waste glass aggregate (WGA) with fly ash in certain proportions was studied by different amounts of molarity and WGA proportion on geopolymer concrete (GPC). For this aim, the molarity values of the NaoH concentration consumed in this investigation were determined as 11, 13 and 16. At the end of the examinations, workability, setting time, compression strength (CS) test, splitting tensile (ST) tests and flexural strength (FS) tests are performed. The conclusions demonstrated that the slump values increased as the molarity increased and waste glass (WG) percentages decreased. While concerning CS, ST and FS examinations, as the proportion in the combination was increased, these test results tend to decrease correspondingly. While the proportion of molarity of NaOH proportion was altered from 11 to 13 and 13 to 16, these test results tend to increase. This examination study demonstrates that glass aggregate had also a slight adverse influence on capacity and workability. Moreover, the use of 10% glass aggregate with NaOH molarity of 16 is suggested to gain the optimum sustainable GPC considering both fresh and hardening properties as the combined influence of WGA and NaOH molarity. Furthermore, in this examination, the offered strength models are established and related to those built on several standard codes. More importantly is that an equation is derived to predict the compressive strength of the geopolymer mixture utilized in this study. Additionally, scanning electron microscopy (SEM) analysis was achieved on the example parts attained from GPC examples formed with WGA.
