Interfacial bond performance and degradation mechanisms of UHPC-normal concrete composites in aggressive environments

Key Points

• Interfacial bond performance decreases significantly in aggressive environments, impacting structural integrity.
• Degradation mechanisms observed include chemical reactions and physical wear, leading to bond failure.
• Analysis focuses on the interaction between UHPC and normal concrete under harsh environmental conditions.
• These findings highlight the need for durable composite materials in construction exposed to aggressive settings.
