In this study, we investigate the properties of aggregates as a fundamental component incorporated in concrete. Motivation for this research is to enhance characteristics of concrete. Our objective is to examine the relationships between the geometric properties of aggregates, the ratio at which different fractions are mixed, and the resulting porosity of the mixture. To achieve this goal, we construct a model of loose aggregate in a container using simulation of physical principles such as gravity and force interactions in the Unity game engine. For generating aggregate particles represented by ellipsoids, we employ the geometric characteristics of fractions from a real aggregate sample. To evaluate our approach, we create multiple models of mixtures containing various fractions mixed in different ratios using our algorithm. We compare the resulting porosity of the models with the actual porosity established through experimentation on real aggregates. The contribution of our work lies in a comprehensive methodology for generating data that is labor-intensive to acquire in a real environment. Our tool enables the formulation of hypotheses about the porosity of aggregate mixtures and their subsequent optimization.
These files constitute a Unity project in which the stone mixing algorithm has been implemented, intended for generating models for a diploma thesis.
