摘要
Fracture surface geometry is often related to material toughness. This approach requires a quantitative description of the fracture surface. The aim of this work was to investigate scale effects on the geometrical features of the fracture surface of polymer concrete (cementless concrete) with different microstructures. Polymer concrete (PC) is a concrete-Eke composite, in which a resin binder substitutes the cement binder. The fracture surfaces were characterized at different magnifications by: fractal dimension, surface roughness ratio and profile roughness ratio. Relationships between parameters describing the geometry of PC fracture surface were analyzed. The main conclusion is that the geometry of the PC fracture surface depends on the scale of observation.
