Abstract

Abstract

To investigate the evolution mechanism and evaluation method of compressive damage in rubber concrete under various influencing factors， compression tests were conducted on rubber concrete specimens， with simultaneous monitoring using acoustic emission technology. This study considered variables such as rubber content， rubber particle size， and loading method. The results indicate that the damage evolution process can be divided into four stages according to the trend of stress development. As the rubber content increased， the fragile area within the specimens expanded， and the corresponding acoustic emission characteristic parameters also increased. With the decrease in rubber particle size， the fragile area first increased and then decreased， and the acoustic emission characteristic parameters exhibited a similar trend of initial increase followed by decrease. Based on the theory of rate process and damage mechanics， a damage constitutive model for rubber concrete was proposed， and a mathematical model of damage evolution using acoustic emission characteristic parameters was established. Finally， a method and criteria for damage evaluation of rubber concrete materials under compression were proposed.
- rubber concrete,
- acoustic emission technology,
