Use of waste glass powder toward more sustainable geopolymer concrete

The influence of waste glass powder (WGP) with fly ash in certain proportions on geopolymer concrete (GPC) was investigated by exchanging different molarity and WGP percentages GPC. For this objective, altered having 10%, 20%, 30%, 40%, the effect sodium hydroxide (NaOH) examined. compressive strength tests, splitting tensile flexural tests were conducted. workability setting time also evaluated. With addition WGP, for molarities (M) 11, 13, 16 NaOH reduced an average 17%, 67%, respectively. findings showed that slump values decreased as increased. Molarity significantly affected time, but had no time. Although high increased capacity, a noticeable negative workability. This study demonstrated slight capacity Furthermore, when combined effects taken into account, use 10% M13 recommended to obtain optimum sustainable GPC considering both fresh hardening properties. Scanning electron microscopy (SEM) analysis done samples, too.
