Damage Characteristics of Uniaxial Compressed Concrete Embedded Different Aging Rubber by 3D Mesoscale Model

Rapid development of the automobile industry has brought disposal problem waste rubber tires. Mixing tires into concrete can not only solve environmental problems but also improve mechanical properties concrete. Rubber aging is one main factors to affect rubberized Therefore, an FEM model in mesoscale established this paper. The influence on uniaxial compression damage u;studied. results show that (1) elastic modulus and compressive strength are negatively correlated with level content positively particle size rubber. (2) After enters softening section, crack resistance (3) Compared modulus, more sensitive change parameters rubber, is, range always greater than its when level, content, change.
