This study investigates the degradation potential of metakaolin-based geopolymer (GP) composites when exposed to real and simulated acidic environments. Traditional OPC concrete, commonly used in wastewater treatment facilities, faces considerable deterioration due destructive chemical composition municipal wastewater. extensive investigation aims assess performance GP as a sustainable alternative such materials. The mortar samples were prepared subjected immersion primary clarifier unit at local plant (real) laboratory-made acetic acid solution (simulation) for up four weeks after curing. analysis included measurements % strength weight loss, well characterization techniques isothermal calorimetry, microstructure (SEM), mercury porosimetry (MIP). outcomes signified cumulative heat generation 534 J/g three days, with an average compressive 79.4 MPa past 28 days. Exposure led 13% decline 3.90% loss sample weight, while exposure resulted 18% 5.60% loss. Observations from SEM revealed microstructural changes, including formation biofilms air voids, indicating multifaceted interactions between matrix its surrounding environment. research effectively highlights improve durability against conditions, suggesting future applications construction infrastructure harsh
