The paper conducts chemical analysis of extracted cement powder sample through core drilling,stratified cutting and scouring,putting concrete specimen into sodium sulphate solution based on a certain period then air-drying for forming the cycle of dry and wet,tests the ion content of sulphuric acid radical in concrete of different length of time and different depth and studies the law of influence of different solution concentration of sodium sulphate and different erosion time to the ion transmission of sulphuric acid radical in concrete.The outcomes show that a) the ion content of sulphuric acid radical decreases continuously with the increase of depth under the same erosion period;b) concrete has complicated relativity affected by the depth of erosion,ion content of sulphuric acid radical and concentration of sodium sulphate solution and erosion time.Low concentration solution makes concrete greater depth of erosion while lower ion content of sulphuric acid radical.High concentration solution makes concrete smaller depth of erosion while higher ion content of sulphuric acid radical and;c) when erosion time is greater than 360 days,the surface of concrete peels off.The depth of denudation increases with the increase of solution concentration,resulting in decrease of ion content of sulphuric acid radical which affects the scope of depth.
