A compression loading setup was both designed and fabricated. The chloride diffusion coefficients of recycled aggregate concrete under compressive stresses were measured by the rapid chloride ion migration (RCM) method. The experimental results show that the chloride diffusion coefficients of recycled aggregate concrete (RAC) under different compressive stress ratios generally decrease with the increase of curing age. For RAC subjected to the same compressive stress ratios, the chloride diffusion coefficients approximately have power functions with curing ages and the relationship models are proposed. Moreover, the influence of curing age on chloride diffusion coefficient firstly decreases and then increases as the compressive stress ratio increases. %K recycled aggregate concrete(RAC) %K chloride diffusion coefficient %K curing age %K compressive stress ratio %K rapid chlorideion migration(RCM) method %U http://tnuaa.nuaa.edu.cn/ch/reader/view_abstract.aspx?file_no=20180213&flag=1
