Abstract
The article is synthetically revealed the erosion deterioration law of concrete under double-factor erosion condition in complex environment, research results indicate: within a short period of time, the combined action of double factors which are chlorine ion and sulphate ion changed the change laws of single factor effect of chloride ion or sulphate ion. Under the combined action of double factors, there does not appear simple superposition of concrete’s erosion effect, while there appears drag effect each other in short time, crush resistance, fracture resistance and anti-erosion coefficient appear the change law of decreasing after increasing, at the early stage of being in erosion for the city underground structure, the role of double factors delayed the decreasing of erosion resistance coefficient.
