## 1 Introduction
In the premises of rock quarries, a massive quantity of fine dust particles can be found suspended in the air or accumulated near the stone crusher, which are hazardous for human health, animals, and plants [20]. It is, therefore, necessary to find a new way to recycle this waste. This waste material can be utilized efficiently in the construction of infrastructures as a partial replacement for cement and aggregates. There are several studies highlighting the incorporation of quarry wastes, mostly limestone and dolomite powders as aggregates in geopolymers [22; 23; 24]. However, the data available on the incorporation of quarry wastes (limestone and dolomites) as a partial replacement of binder in GPC is limited. A few researchers have highlighted the use of this waste as a geopolymer binder in GPC mixes. [PERSON] et al. (2019) studied the integration of dolomite-based quarry dust waste material as a partial replacement of cement and FA in cement-based (CEM) and FA-based geopolymer mortars, respectively [9]. The FA was replaced by quarry dust wastes at five different percentages, i.e., 0%, 10%, 20%, 30%, and 40% by weight of total geopolymeric binder. The results confirm that quarry dust wastes can be incorporated, even at a high replacement level (40% by weight), in cement-based and FA-based geopolymer mortars, demonstrating good and, in certain cases, better mechanical and durability properties. It was found that compressive strength was increasing with the increase of quarry waste content for both CEM- and FA-based geopolymer mortars [9]. Hence, the utilization of quarry dust waste materials would not only create economic and environmental benefits for construction, but also deliver an effective and green disposal solution [9]. One of the significant problems in utilizing GPC for structural members is its brittle behavior, with low strength in tension and flexure as compared to conventional concrete [25,26]. [PERSON] studied the utilization of steel fibers in GPC to cope with the brittle behavior [27]. Several studies inspected the influence of various types of fibers, i.e., cotton, polypropylene, polyvinyl alcohol and steel fibers, in GPC to lower its brittleness [28, 29, 30, 31, 32]. The inclusion of carbon, polyvinyl alcohol and polypropylene fibers in GPC are found to have inadequate resistance to elevated temperature, weak bond strength, and high sensitivity to solar radiation [31]. However, the presence of steel fibers in GPC are found to enhance ductility by improving the tensile and flexure strengths, controlling the crack width and energy absorption capacity [33]. The effectiveness of steel fibers in GPC relies on numerous parameters, including the fiber content by weight or volume, strength, geometry and aspect ratio [33]. Many studies have been reported on GPC, with the major focus of research on the evaluation of the engineering properties of GPC mixes, such as mix proportion development, effect of source material on physical, chemical, microstructural, mechanical, rheological, and durability properties [33]. Some studies are also available on the behavior of GPC structural members, which highlight equally good and, in certain cases, better performance than conventional concrete [34, 35, 36, 37, 38]. [PERSON] et al. (2005) investigates the behavior of FA-based GPC beams (200 \(\times\) 300 \(\times\) 3000 mm). The test results reported that loading capacity, load deflection behavior, and failure patterns were almost like those of reinforced cement concrete (RCC) beams [35]. [PERSON] et al. (2007) studied the behavior of FA-based GPC columns (175 \(\times\) 175 \(\times\) 1500 mm) tested under different loading eccentricities. The experimental results suggested that FA-based GPC columns have the potential to be used in structural applications [38]. [PERSON] (2009) evaluated the shear and bond behavior of reinforced GPC beams. It was reported that cracking patterns and loading capacity of GPC beams were analogous to RCC beams [36].
