Compressive　strength　is　one　of　the　factors　affecting　the　permeability　of　concrete.　Almost　all　of　the　concrete　had　contained　supplementary　cementing　materials,　which　caused　in　the　effect　of　strength　on　permeability　of　concrete　to　be　more　complex.　In　this　paper,　different　strength　of　concrete　are　prepared　based　on　different　water-cement　ratio,　the　different　types　and　content　of　supplementary　cementing　materials,　and　electric　flux　and　chloride　ion　diffusion　coefficient　of　different　strength　of　concrete　are　tested.　Experimental　results　show　that　besides　of　strength　of　concrete,　the　permeability　of　the　concrete　are　related　with　content　of　supplementary　cementing　materials,　while　the　permeability　is　not　related　with　types　of　supplementary　cementing　materials.　The　results　of　this　study　can　provide　some　referenced　guidance　for　concrete　durability　design.
