Abstract
Section restoration method is one of the way to extend service year of RC structure. However, even there is a difference of characteristic between concrete and section restoration material, still there is a lack of research. Therefore in this study, chloride diffusion coefficient and concentration are predicted by RCPT and FEM. As a result, diffusion coefficient of section restoration material is 0.44×10-8㎝2/sec which is about one-seventh of concrete(3.18×10-8㎝2/sec). Also, the result of FEM, un-repaired structure(R=0㎜), its service year will be 16years, meanwhile repaired structure can maintain 48years(R=10㎜) to over 100years(R=50㎜).
