抄録

The aim of this research is to reveal the effect of curing conditions on carbonation and chloride diffusion of normal concrete and fly ash replacement concrete. Sealed curing, air curing and curing under the wind and sunlight were compared to normal water curing. As the result, better curing made carbonation depth, chloride diffusion coefficient and void ratio of cement matrix were low, and in case of fly ash replacement concrete, mass transfer resistant was lower by comparison of same void ratio of normal concrete. According to the analysis of binarized concrete CT image by homogenization methods, magnitude relation of tortuosity between normal concrete and fly ash concrete is differ in the difference of water to powder ratio. This fact implies that the mechanism of high mass transfer resistance performance of fly ash concrete is different in differ of pore structure of each solid.
