The long-term durability of basalt fiber-reinforced geopolymer concrete (BFRGC) in marine environments is importance for the development sustainable construction practices. This study examines exposed to dry-wet cycles and immersion treatment conditions. A with 1% fiber content was prepared subjected treatments a 5% sulfate solution (Tehmina et al., 2014; Nasir 2016; John 2016) [1-3]. Density measurements, ultrasonic pulse velocity tests, uniaxial compression tests were conducted on BFRGC after various durations. mechanical properties compared without fibers environments. Additionally, changes compressive strength different further discussed. Using low-field nuclear magnetic resonance (LF-NMR) technology, variations pore structure also analyzed. results show that property loss from greater than treatment. In BFRGC, decreased by 10.1% 192 days cycles, smaller decrease 5.6% inclusion effectively enhances stability. When cycle 49.6 MPa 44.6 MPa, reduction 10.1%. Conversely, dropped 49.7 42.1 15.5%. LF-NMR test porosity increased 21.6% 17.5% environments, respectively. contrast, 16.1% 12.7%.

The increasing global emphasis on sustainable construction practices has spurred significant international research into developing durable and eco-friendly concrete materials. This study investigates the potential of metakaolin glass powder as supplementary aluminosilicate materials in slag- based geopolymer mortars, aiming to enhance their mechanical properties durability. To further improve performance, polypropylene fibers were incorporated at various dosages. Therefore, 13 mixtures mortar blast furnace slag have been developed. control mix does not contain or replacement materials, whereas other formulations, employed substitutes for weight percentages (relative slag) 5% 10%, separately combination. Additionally, fiber-containing samples are divided two groups volume percentage fibers, comprising 0.2% 0.4%. results investigation show that use powder, particularly a leads an improvement 28-day compressive strength. Furthermore, mixes containing demonstrated higher flexural strength compared those metakaolin, irrespective fibers. best performance rapid chloride permeability test is associated with combination 10%. Satisfactory obtained when using this utilized fuzzy inference system predict indicate that, by considering uncertainties, can be predicted error less than 1% without need complex mathematical calculations.
