Summary
Research demonstrates that surface treatments can significantly enhance the weather protection and earthquake resistance of unburnt brick masonry, a critical material for preserving historic structures like Bam's UNESCO-listed Arg-e-Bam citadel. The study, conducted by the Technical University of Dresden in collaboration with Iranian cultural authorities and UNESCO, evaluated various surface treatments to improve shear strength and durability. Climatic chamber tests revealed that specific additives and render techniques effectively mitigated weather-related degradation while maintaining structural integrity. These findings provide actionable strategies for conserving earthquake-damaged heritage sites, particularly those constructed with unburnt brick masonry.
