Abstract:
The morphology of aggregates has been extensively studied in various fields, including physics, geotechnical engineering, and biology, wherever there is an interest in understanding the influence of particle shapes on a system. Concrete, for instance, contains more than 60% of its volume occupied by fine and coarse aggregates, and their morphologies have a significant impact on the structural behavior of the material. The aim of this research is to propose a method for characterizing the morphology of individual and bulk particles, with the goal of incorporating it into the mixture design of cement-based materials. In this study, 3D structured light scanning is used to characterize the morphology of individual particles obtained from the New England region, while the morphology of the bulk is parameterized using the power law. While the conventional mixture design only considers the size distribution of aggregates, the results provide insights that could potentially lead to the consideration of particle morphology in the current mixture design.
