###### Abstract
Potassium hydroxide (KOH), potassium silicate (K\({}_{2}\)SiO\({}_{3}\)), sodium hydroxide (NaOH), and sodium silicate (Na\({}_{2}\)SiO\({}_{3}\)) are utilized as alkali activators in the activation processes [17; 18; 19; 20]. In geopolymers produced through alkali activation, the C-S-H gel observed in traditional Portland cement is replaced by N-A-S-H or C-A-S-H gel [21; 22]. The influence of this gel is crucial in the strength mechanism of geopolymers. Additionally, the Si/Al ratios in the structure of binders used in the mixture also impact the bonding structure [23; 24]. Generally, heat curing is required for geopolymers to gain strength [25; 26; 27]. While 60-80 \({}^{\circ}\)C is sufficient for BFS and metakaolin-based geopolymers [28; 29], FA-based geopolymers require a temperature range of 80-110 \({}^{\circ}\)C [17; 30]. Factors such as curing temperature, curing duration, binder quality depending on coal combustion, binder content, aggregate type, water amount, activator ratio, activator type, and curing conditions are important in the strength mechanism [17; 31; 32; 33]. Geopolymer concretes exhibit early and high strength, high-temperature resistance, freeze-thaw resistance, resistance to wetting-drying cycles, and abrasion resistance compared to traditional concretes. They also demonstrate lower drying shrinkage [34; 35]. However, some studies indicated lower resistance to acids and sulfates than traditional concretes [36]. Conversely, resistance to acids and heavy metals was reported in certain studies [37; 38]. According to the literature, a high CaO content in binders is necessary to perform curing at room conditions. Therefore, FA, BFS, and LP were used in this study. Furthermore, LP was employed to enhance the workability and early setting time of geopolymers [39]. In a study of the physical properties of geopolymer mortar using C-class fly ash, [PERSON] et al. reported in 2015 that the density increases and the flow and compressive strength decrease when the percentage of FA increases [40]. [PERSON] et al., in their 2020 study, found that using FA resulted in an improved compressive strength [31]. In their 2019 study, [PERSON] et al. further revealed that an increase in FA content led to a decrease in setting time [41]. Moreover, in 2010, [PERSON] et al. investigated the effect of BFS on fly ash-based geopolymer characteristics and proved that an increase in BFS percentage led to an increase in compressive strength and a decrease in setting time [42]. [PERSON] et al. reported in 2013 that compressive and flexural strength were decreased when the BFS content increased [33]. In 2016, [PERSON] deduced that by increasing BFS, water absorption decreased [43]. The 2021 study of [PERSON] et al. on the effect of LP in geopolymer established that an increase in the amount of LP was accompanied by a decrease in dry unit weight, compressive strength, and flexure strength [44]. In 2017, [PERSON] et al. proved that the use of LP in high proportionsleads to a decrease in compressive strength, flexure strength, and water absorption and an increase in setting time [45]. In 2021, [PERSON] et al. deduced that the setting time increased at the same time the compressive strength and flexure strength decreased when the percentage of LP increased [46]. The meticulous choice of materials holds utmost significance in geopolymer production, exerting a profound impact on the ensuing material characteristics. Through a thorough investigation, the authors identified a conspicuous gap in the existing literature concerning the simultaneous incorporation of FA, BFS, and LP materials in the production of geopolymers. For instance, extant research has explored the synergistic utilization of FA and BFS in combination [10; 11; 12], the exclusive use of FA [16; 17; 23; 27], the exclusive utilization of BFS [15; 16; 17; 18; 19; 20; 21; 22; 23; 24; 25; 26; 27; 28; 29; 30; 31; 32; 33], and the exclusive use of LP [39; 45; 46]. There remains a need for exploration into the combined incorporation of all three materials.
