In this research, the performance of fly ash/GGBS geopolymer mortars made with different quarry waste powder as filler materials by substituted the river sand fine aggregate with different ratios was evaluated based on the mechanical, physical, durability properties and microstructural analysis. Limestone waste, marble waste and basalt waste powder were used as filler materials developing eco-friendly and economical geopolymer from industrial waste as a promising sustainable area of research. A series of tests were conducted such as on strength properties, ultrasonic pulse velocity (UPV), physical properties, abrasion resistance test, splitting tensile strength and microstructure analysis (SEM). The samples were elevated at the high-temperatures of 200 degrees C, 400 degrees C, 600 degrees C and 800 degrees C. Results conducted that the use of limestone waste powder and marble waste powder up to 50% ratio improved the geopolymer composite's strength. The three filler geopolymer composites positively affected water absorption, strength properties and abrasion ratio results. The current article's finding has indicated a potential solution, presenting another geopolymer class followed by the successful use of fly ash and quarry waste as significant asset materials. The output of this study is commercially expected to be effective intercession for waste recycled and friendly environmental management conclusions.
