Evaluation of the Stress–Strain Behavior of Rubberized Concrete under Quasi-Static Compression
Benefiting from its excellent sustainable plastic carrying capacity, rubberized concrete (RuC) has received extensive attention. In this study, the dependency of rubber aggregate (RA) particle size influencing factor on content is investigated through quasi-static compression tests. The results demonstrate that the influence of RA particle size on stress–strain behavior of RuC shows a content-dependent effect. The postpeak stress-buffering area and strain-softening area of RuC reduce significantly with the increase of RA particle size at higher RA contents. Moreover, the corresponding rubber aggregate influencing factor (RIF) model is established. The constitutive model of RuC is proposed by introducing the RIF model into the characteristic parameters. Finally, the stress–strain relationship of RuC is predicted by using the proposed constitutive model. It is concluded that the proposed constitutive model can be further applied to the structural design optimization of RuC.
