摘要(中) 本研究係應用電化學技術,研究通電電流在發生鹼質與粒料反應之
硬固無筋混凝土內的分佈行為。本研究主要設計參數為輔助陰陽極之間
距、數量、與排列方式。其目的是為了瞭解輔助陰陽極在無筋混凝土內
之不同間距、數量、與排列方式對通電電流所產生的影響。
研究成果顯示,混凝土試體進行電化學通電時,電極平行配置之混
凝土試體,其電流強度最強的區域發生在陰陽電極間之直線區域上。而
混凝土內離子的析出效果,主要與陰陽輔助電極之表面積與通電電流密
度成一正比關係。
摘要(英) The experiment applied the electrochemical technique to
investigate the distribution of electric currents that in the harden nonreinforcing
concrete arose from the alkali- aggregate reaction. The
major design parameter are the distance, amount and permutation of
the auxiliary electrodes. The purpose of the electrode parameters
design was to analyze the influence on the concrete.The results show that when applying electrochemical technique for
our experiment, the specimen which disposed for parallel-electrodes
existed a strong electric intensity on the beeline-area of the anode
and cathode. And the result of the ions separate from the specimen
was depended on the surface area of the electrodes and electric current density.
