文摘
- •
Stress relaxation process of CA mortar under different initial strain levels was elaborated.
- •
Microscopic change in the process of stress relaxation was analyzed.
- •
The isochronous stress-strain relationship of CA mortar was obtained.
- •
An established model can effectively reflect the relationship between the stress relaxation and initial strain level.
