This volume investigates the critical role of the interfacial transition zone (ITZ) in determining the mechanical and durability properties of cementitious composites. The authors, a group of international experts in materials science and civil engineering, compile research presented at the Second International RILEM conference to synthesize current understanding of the microstructure and performance of the ITZ. By examining the chemical and physical interactions at the boundary between cement paste and aggregates, the text provides a framework for predicting how these zones influence the overall structural integrity of concrete materials.

Experts in the field of concrete technology recognize this volume as a foundational reference for understanding the microscopic behavior of cementitious materials. Researchers frequently cite the proceedings for its technical depth and its role in standardizing the study of interfacial phenomena in modern construction materials.
