This Ph.D. thesis discusses the mesostructure of concrete, and the developed theories are used for computer simulation of the mesostructure of concrete and for estimation of the size effect on fracture energy of concrete. Objectives include: To derive the exact solutions for the aggregate size distribution of concrete based either on the equal volume fraction mix or on the Fuller mix. To establish a theory of aggregate volume fraction with wall effect for concrete elements of an arbitrary shape. To establish a theory of aggregate size distribution with wall effect. To put forth a modified fractal model for the size effect on fracture energy of concrete.Civil Engineering
