It is one of the most important aspects among the mechanics to research on the destroy behavior of concrete which has inner micro-cracks defect already.By experimental methods,the paper discusses the relationship between the development of micro-cracks and the fatigue evolvement,it is concluded that both the fatigue evolvement and the elastic modulus depression are not only decided by the initial density of inner micro-cracks,the results may be information for further theory search.
