In order to measure the corrosion of steel in mortar-embedded corroded steel, nondestructive techniques such as the electro-potential method and the transient electro-magnetic(TEM) method were adapted. After steels were corroded by the salt spray during 0, 4, 8, 15, 25days, they were embedded in mortar which were made form water : cement : sand ratio of 0.5 : 1 : 2. The mortar specimen was 50㎝ long, 20㎝ wide and 10㎝ thick.
The contents of result acquired in this study are as follows.
(1) The variation of the potentials and the secondary electro-magnetic forces were shown by change of steel surface with different corrosion time of steel
(2) The values of the potential of mortar specimen embedded steel were increased with cover depth and the values of the secondary electro-magnetic force of that were .decreased with cover depth
