초록
We conducted this study to develope technique for removing fine mortar attached to waste reinforcing steel bar (D13). We observed the effect of the glycolic acid concentration (10 ~ 40%) and reaction time (0.5 ~ 4 hr) on the mortar removal. The reaction rate (−1.3089 hr−1) was the fastest at 20% of glycolic acid. The mortar was completely removed in 3 hrs. The reaction rate decreased with pH increase (1.4 ~ 2.0) at 20% of glycolic acid.
