Abstrakt: The soda-lime glass is recognized as one of the best recyclable materials. However, surface contamination of glass waste or bulk impurities in the glass matrix can significantly alter glass properties limiting its direct reuse in the glass industry. As an alternative utilization strategy, the incorporation of waste glass as a partial replacement for sand or binder in concrete-based materials for sustainable construction applications has shown promise. Nevertheless, impurities in glass that may affect the alkalinity of concrete or calcium-silicate-hydrate formation must be carefully considered. For example, when the glass waste is in the form of shards or small fragments (particles), the potential diffusion of metal ions into the environment (e.g., through reaction with rainwater) becomes an important issue. In this work, we perform wet chemistry treatment on the recycled glass particles obtained from the commercial source. The resulting changes in glass particle properties were analyzed using microscopic and spectroscopic techniques. In particular, changes in the concentrations of Mg, Al, Ca and Na near the particle surfaces were detected, indicating potential to elements release to the environment via leaching. The observed results can be helpful in the explanation of processes at interfacial transition zones in waste glass containing concrete-based materials.
