Özet

Geopolymers are an important composite material alternative to cement with high CO2 emission, which allows

the use of waste materials in its structure. However, which waste material contributes to the geopolymer

composite structure to what extent is still an ongoing research area. This study has been prepared to contribute to

closing the gap in this field. In this study, industrial waste materials (waste marble powder (MP), waste brick

powder (BP), ceramic waste powder (CW), waste glass powder (GP), and rice husk ash (RHA)) were used 25%,

50%, and %75 percentage as aggregate instead of recycled concrete (RC) on red mud-metakaolin based geo-

polymer mortars. Mechanical properties (ultrasonic pulse velocity (UPV), splitting tensile, compressive, and

flexural strengths), physical properties (void ratio, water absorption, unit weight, and workability properties),

abrasion test, and microstructure analyzes (SEM-EDS and XRD) were performed. The highest compressive

strength results were in seen the 25% brick powder substitution, with an increase of 74.01% compared to the

control sample. Also, the compressive strength results increased in the case of increasing the use of ceramic

waste. High silica and alumina contents in both materials were effective in these cases. In terms of the abrasion

test, the highest performance was seen as a 49.2% decrease in the mass loss in 75% marble powder replacement.

As a result, substitute materials have shown a successful performance, creating significant potential in the

production of a sustainable geopolymer
