A DEM-based framework to optimize the gradation of concrete aggregate
It has been reported that the grading of aggregate has a very obvious effect on the mechanical properties of concrete, and well-graded aggregate has a larger packing density and a smaller voidage [7, 8]. Therefore, it is of great significance to study the influence of aggregate size distribution on the mechanical properties of concrete.
