STUDY ON RELATIONSHIP BETWEEN CHLORIDE DIFFUSION IN CONCRETE AND TIME

摘要：

The resistance of concrete to chloride ion diffusion is one of durability indicators,and the chloride ion diffusion in concrete reduces with erosion time,it is more difficult to obtain relationship between chloride diffusion in concrete and time. A series test to study the relationship is designed in this paper,diffusion coefficients in concrete of different mix proportion after 28d,40d,80d,120d,160d and 200d are measured in NEL method. The result show that diffusion coefficients in concrete of all mix proportion are all decrease with curing time,and there is slow trend of decrease range of diffusion coefficients with time.
