Abstract

This study is to investigate on the remaining life of reinforced concrete apartment by using the probability of a reinforcing-steel corrosion and the carbonation tendency of domestic reinforced concrete apartments by using the statistic method. The results are as follow. ·To compare with the carbonation velocity of Kishitani's formula (x=3.727{{{{ SQRT { t} }}) when water-cement ratio is w=0.6, R=1, it is founded out that the carbonation velocity is slow a little in all area investigated and inland area, and fast a bit in coastal area. ·In the influencing factors in regard to the probability of reinforcing-steel corrosion, It seems that the influence of elapsed time is more effective than that of region. Therefore, it is necessary that it makes sure of the cover depth under apartment construction in recent so far as the durability is considered.
