## 1 Introduction  
On 6 February 2023, two separate earthquakes in Kahramanmaras inflicted extensive damage throughout 11 provinces, obliterating a significant portion of the regional infrastructure and resulting in almost 50,000 fatalities [1, 2]. These natural disasters have reiterated the necessity to enhance construction technology in seismic regions. Current economic difficulties, resource scarcity, and environmental pollution have prompted the utilization of durable, sustainable, and cost-effective materials [3, 4, 5, 6]. Fiber-reinforced polymers (FRPs) are extensively utilized in fortifying structures impacted by earthquakes. Carbon-fiber-reinforced polymers (CFRPs) and glass-fiber-reinforced polymers (GFRPs) provide efficient solutions for the reinforcement of structural components [7, 8]. Nonetheless, FRP applications are constrained by elevated costs, challenges in adhering to moist surfaces, and diminished performance at elevated temperatures [9]. In this context, it is crucial to examine alternative materials, such as repair mortars. Polymer-modified repair mortars are extensively utilized in structural restorations owing to their exceptional strength, flexibility, and robust adhesion to existing concrete structures [10; 11; 12]. Moreover, repair mortar provides a more cost-effective alternative to epoxy, enhancing structural integrity by reinforcing components. In recent years, utilizing sustainable and eco-friendly materials in the construction sector has gained significant importance. Research on utilizing virgin and recyclable hemp fibers as external wrapping reinforcement in reinforced concrete beams has garnered interest. Hemp fibers are regarded as an alternative to CFRPs and GFRPs and have undergone tensile tests, compression tests, and four-point bending tests; furthermore, the adhesion and tensile strength of the epoxy used in their wrapping were also assessed. These tests demonstrate that virgin hemp fibers possess significant load-bearing abilities and offer environmentally viable alternatives [13; 14; 15; 16]. Geogrids are utilized to inhibit crack development in the tensile regions of reinforced concrete structures and to enhance load-bearing capacity. Geogrids can enhance fatigue strength and postpone crack formation in reinforced concrete components [17; 18; 19; 20; 21; 22; 23]. In a previous study, fiberglass geogrids installed at a depth of 15 mm exhibited a 35% increase in load-bearing capacity relative to the control specimens [22]. Research indicates that concrete beams reinforced with geogrids maintain their structural integrity despite total failure [24]. [PERSON] et al. [25] compared the performance of steel and biaxial geogrids in reinforced concrete specimens, demonstrating that the geogrid-reinforced slabs exhibited a 25% enhancement in load-bearing capacity, a 6.5% increase in deflection, and a 23% improvement in energy absorption relative to steel-reinforced slabs. The data suggest that using geogrids in reinforced concrete parts enhances performance. [PERSON] et al. discovered that employing geogrids as external column restraints markedly enhanced the strength, ductility, and energy capacity of reinforced concrete columns [26]. Similarly, research on the application and advancement of steel reinforcement in structural elements has indicated an enhancement in load-bearing capacities [27; 28; 29; 30; 31]. In their research, [PERSON] et al. used geogrids as reinforcement in mortar. The research investigates the strength characteristics of mortar augmented by geogrid reinforcement. Mortar specimens, both with and without a geogrid, were produced and subjected to tensile, compressive, and flexural testing. The tensile and flexural strength of mortar using a geogrid were seen to be enhanced [32]. [PERSON] et al. investigated the improved capabilities of brick masonry prisms and panels reinforced with a geogrid integrated into brick mortar. Geogrid-reinforced brick panels demonstrated superior crushing load, in-plane shear strength, lateral strength, and ductility.
