本研究主要探討不同主筋數量及間距對鋼筋腐蝕量測技術之影響。試驗過程中以水灰比0.6之水泥砂漿製作含不同主筋與箍筋配置之試體，再將養護28天後之水泥砂漿試體靜置於3.5%鹽水中進行通電加速鋼筋腐蝕，並於每天使用脈衝電流法、直流極化法、交流阻抗法量測鋼筋腐蝕電流密度，據此計算鋼筋腐蝕速率與腐蝕量，再與重量損失法所得實際腐蝕量進行比較。研究結果顯示，脈衝電流法、直流極化法及交流阻抗法所量測出的計算腐蝕量百分比皆低於實際腐蝕量百分比。無箍筋時，各量測法的量測值隨著實際腐蝕量的增加而更接近實際重量損失。含雙根主筋但主筋間距較大之試體所量測的結果與單根主筋試體相近，但將雙根主筋間距縮小時則量測值較不準確。

This study discusses the influences of the amounts and spacing of the bars on the reinforcement corrosion measurements. During the study, cement mortar specimens at water-cement ratio of 0.6 were prepared with different main bar and stirrup locations. The specimens were cured in limewater for 28 days and then immersed in 3.5% salt water and finally subjected to accelerated corrosion. The reinforcement corrosion current density was measured using the galvanostatic technique, linear polarization, and the AC impedance each day. The corrosion rates and amounts of corrosion were calculated and compared with the actual weight losses. Results showed that all the calculated weight loss percentages were lower than the actual weight loss percentages. In the absence of the stirrups, the measurements were close to the weight losses as the actual weight losses were increased. In the presence of double main bars with a large spacing, the measurements were close to those in specimens with single main bar. When the spacing was reduced, the measurements were less accurate.
