The results of earlier experimental work and numerical calculations to determine the effects of technological parameters on abrasion resistance of concrete are summarized and new data presented. The dependences of the near-surface stress-strain state on the geometric and stiffness parameters are analyzed. Particular attention paid to the stages preceding the destruction of the adhesion interaction between cement matrix and grains. Numerical calculations were carried out in the ANSYS software. This numerical model may be useful for understanding heterogeneous material behavior in terms of wear, depending on structure geometrical characteristics, material mechanical properties and interactions occurring in the near surface layer. Adhesive laws gives very interesting advantages, of which the most important is to model the evolution of damage throughout the life of the building constructions. |
