## 1 Introduction
The inclusion of calcium-rich materials in GPC can accelerate FA dissolution and improve reaction product formation at ambient curing conditions [23]. The incorporation of SG in GPC results in better engineering properties at ambient conditions [3; 4; 24; 25]. Several studies have been carried out to investigate the effect of SG on the fresh, mechanical, and durability properties of GPC [3; 4; 16; 23; 24; 25]. The QRD is a calcium-rich waste material of the rock crushing industry that is produced as a cloud of unwanted dust during the manufacturing process of coarse aggregates. A portion of this unwanted waste is often used on-site as a filling material for the quarry pits. This waste can be effectively used as a construction material to preserve the environment and natural resources. The QRD has been used as a partial replacement of sand in GPC [24] and mortars [25]. The consumption of QRD in concrete is recommended mainly in the regions where the sand is not available in abundant quantity [26]. The suitability of QRD to be used as a sand replacement material shows superior mechanical properties of concrete such as compressive, tensile, and flexural strengths [26; 27; 28]. The complete replacement of sand with QRD gave superior compressive strength properties [29]. The QRD having a surface area of 6000 cm\({}^{2}\)/g can be utilized as a precursor to making alkali-activated binders [30]. It was identified that a combination of an equal amount of QRD waste and OPC contents usually reduced the superplasticizer (SP) requirements and enhanced the compressive strength of OPC concrete cubes [27]. Some studies have used QRD as a partial replacement of sand in GPC concrete [28; 31; 32; 33; 34; 29]; however, studies on the development of a GPC mix by blending quarry rock dust (QRD) wastes as a binding agent are rather limited [36; 37]. This study has been undertaken to investigate the effects of QRD wastes as a binding agent on the engineering properties of GPC mixes containing low calcium FA and SG. The QRD waste is used as a partial replacement of SG (a binder material) in the QRD, FA, and SG-based GPC (QFS-GPC) mix to produce eco-friendly construction material. The SG was replaced by 0%, 5%, 10%, 15%, and 20% of QRD. The objective of the present study is to observe the performance of QFS-GPC for workability and mechanical properties at ambient temperature curing conditions. According to the building codes, structural concrete members should fulfill the fire safety requirements [36; 37] since the buildings may be exposed to fire hazards. Generally, the best fire resistance properties of concrete are achieved by alkali-activated mortars (AAMs) when used in construction as building material [32]. Therefore, in the present study, the fire resistance properties such as the residual compressive strength and the weight loss of the QFS-GPC mix specimens will also be determined at elevated temperatures, i.e., 400 and 800 \({}^{\circ}\)C by heating the specimens in a controlled electric furnace. In the current study, the main intension of using QRD waste as geopolymer binding material is to meet the annual production of concrete due to limited production of FA, SG, and other waste materials. The use of QRD as a geopolymer binder is very limited as it has only been used as a filler material. The performance of QRD-incorporated fly ash (FA) and slag (SG) based geopolymer concretes exposed to ambient and elevated temperatures is investigated. An optimal mix of QFS-GPC will be ascertained based on the performance criteria mentioned above. Moreover, the contributing influence on the mechanical and thermal resistance properties of geopolymer concrete was focused and discussed herein.
