Unreinforced masonry panels are the most important supporting elements in many structures, but these building elements are very vulnerable to earthquakes, and serious damage occurs. Many researchers state that the seismic performance of the masonry samples is poor and that these elements should be strengthened. In this study, the structural behavior of the strengthened masonry prism was investigated using Geogrid Geopolymer Panels (GGP) in compression tests. Six stone masonry wallettes were built to characterize them under loading systems, and the behavior of the samples was determined with different geometric strengthening methods (cross, diagonal, and parallel). Samples UCT-M1 and DCT-M1 were unreinforced masonry walls. GGP material was applied across the entire surface of reinforced samples UCT-M2 and DCT-M2. Vertical and diagonal compression tests were applied to the samples according to ASTM C1314-10 and ASTM E519-02, respectively. A linear variable differential transducer was placed on the samples, and the load-displacement curves were determined. As a result, the reinforced masonry walls had higher mechanical strength and load-carrying capacity than the UCT-M1 and DCT-M1 samples. The geopolymer composites prevented the degradation of the UCT-M2 and DCT-M2 samples. Also, the strengthened specimens displayed more ductile behavior, which depends on the failure mode and cracks patterns under the loading systems.
