Effect of Artificial Lightweight Aggregates on Interfacial Transition Zone in Concrete
Lightweight concrete has a history of more than two-thousand years and its technical development is still proceeding. Despite the diversity of lightweight aggregates available, some mechanical problems have limited their use as structural elements in the construction industry. In general, the mechanical properties of lightweight concretes are lower than normal weight concretes, being affected by factors such as the stiffness of the aggregate particles, the cement content and density. For this reason, significant efforts have been devoted to optimizing their dosage and improving their mechanical properties, to make them competent against conventional concretes. This tendency has led to the study of microstructure, particularly the mechanisms responsible for the interfacial transition zone (ITZ) formation, related with absorption and water release. This investigation focuses on analyze the characteristics of morphology of expanded clay and polymeric wastes lightweight aggregates and conclude that the impact of the ITZ on mechanical properties is of considerable significance, leading to modifying its mechanical behavior.
