Creep Behavior of Self-Compacting Rubberized Concrete at Early Age
https://orcid.org/0000-0001-7994-7253
Self-compacting rubberized concrete (SCRC) is an excellent environment-friendly material that can be applied well in road and bridge engineering. In this study, the tensile and compressive creep performance of SCRC at early age were investigated by using the universal testing machine (UTM) and temperature stress testing machine (TSTM). In particular, the tensile creep at different ages, stress levels, and temperatures corresponding to different stages in the cracking process were analyzed. The results indicate that both the tensile and compressive creep deformation of SCRC increase obviously with the increasing rubber content at different temperatures, loading age, and stress level. Creep increase at early age is more significant in SCRC. The compressive and tensile creep coefficient of SCRC also increase with the increase of rubber content. Finally, the compressive and tensile creep of SCRC can be simulated well by the double power law (DPL) model. Therefore, the creep increase is also the reason for cracking risk reduction of SCRC.
