Cementitious Paste-Aggregate Interface in High-Performance Concrete Based on Silica Fume: Insights from a Microstructure of the Interfacial Transition Zone (ITZ)
This study investigates the chemical and mechanical properties of the paste–aggregate interface in High-Performance Concrete (HPC) incorporating Silica Fume (SF). Limestone and dolomite aggregates were used to assess the influence of aggregate type on interfacial behavior. Mechanical tests, including compressive, flexu...
