Analysis of the Physiochemical Interactions of Recycled Materials in Concrete
… is attributed mainly to a larger, more porous interfacial transition zone (ITZ) and to the cohesive failure of the asphalt. It is hypothesized that the detrimental impact on the ITZ is attributable to organic compounds leached from the asphalt in the high pH pore solution. This study proves the …

Concrete microstructure homogenization technique with application to model concrete serviceability
… as cement and aggregate particles connected by interfacial transition zone (ITZ). Defined on a representative volume element (RVE), the relationship between microstructure and macro properties is established. The proposed model is validated by experimental results and then applied in the study …

The microstructure of synthetic aggregate produced from waste materials and its influence on the properties of concrete
… aggregate affects the microstructure of the interfacial transition zone (ITZ) between coarse aggregate and cement paste matrix. The results confirm the benefit of absorbing water from the surrounding paste by the porous aggregate on the ITZ microstructure unless too much and/or too rapid …

Interfacial transition zone composition and bonding in cementitious materials with asphalt-coated particles
… were carried out by principally studying the interfacial transition zone (ITZ) and the interfacial bond energies between asphalt (RAP) and cement paste. Studies of the ITZ were performed using Euclidean distance mapping and image analysis of compositional backscatter electron micrographs of …

Effect of Surface Moisture Condition on Substrate-Repair Concrete Overlay Transition Zone
… of substrate moisture condition on the overlay transition zone (OTZ) of the substrate-repair concrete. The substrate moisture condition can significantly impact the microstructure characterization of the OTZ. If the substrate is too dry, then it may absorb water from the repair material, …
