| Abstract: | In this paper, the crack-nucleation mechanism and dominating factors were systematically investigated. And the uniaxial non-linear curves of stress-strain tested by different experimental methods were analyzed. Then, the relationship between growth and macroscopic mechanical behavior was discussed. The results show that the non linear mechanical study including microscopic defects is very important for the design theory of concrete structure. |
