Abstract:: Rsistivity measurement，resistance to chloride penetration and cube crushingstrength of mineral admixtureconcrete are tested to analyse the variation of resistivity andchloride diffusion coefficient with age and theregression relationship betweenresistivity and chloride diffusion coefficient．Testresults showthat con— crete resistivity increasedwith the increase ofconcrete age and chloride diffusioncoefficientdecreasedwith the increase of concrete age．The effect of double mixing mineral admixture is better than that of single mixing．Chloride diffusioncoefficient increasedwith the decrease of concrete resistivity and has agood inverse regression relationship with each other．
