摘 要：A trial test method is introduced to form and magnify regular interface. Through researching on the carbonation of the magnifying interfacial transition zone（ITZ）, the practical carbonation of the concrete can be simulated. Because the diffusion rate of CO2 in the ITZ is several times greater than that in the bulk paste, the diffusion rate and direction of CO2 will change and form a new carbonation front line. An interfacial effect zone caused by the ITZ will change the distribution of the complete carbonation zone and the partial carbonation zone. One of the important reasons for the formation of the partial carbonation zone was the existence of the interfacial effect zone. Consequently, the method mentioned in this paper provides a new way for researching on the microstructure of the cement based materials during the carbonation process.
