In this paper,free shrinkage analysis of ECC concrete is carried out by Finite Element Analysis method,the influence of size and reinforcement parameters on ECC strength are considered.Analysis results show:Under the same amount of steel reinforcement,with the increase of concrete strength,the greater the humidity inside the concrete,the smallest humidity decrease in the same time;Under the same concrete strength,with the increase of steel reinforcement increment,the internal humidity of concrete increases,and the decrease in humidity is the small-est within the same time.On the whole,the influence of concrete strength on the concrete moisture field is greater than that of steel reinforcement.
