本研究探討二維電場加速鋰離子傳輸技術(ALMT)實務模擬，及不同電極配置形式的ASR抑制成效。模擬實務通電時3種最常使用的電極形式：面對面、面對線及線對線電極模組，混凝土含鹼量以NaOH調整至1.25％ Na2Oeq，角柱試體於室溫養護1個月後，進行60 V定電壓的ALMT試驗為期一個月，陽極電解液分別使用LiNO3及LiOH．H2O溶液，使用0.5 N及1.0 N二種濃度，通電後的試體置於ASTM C1293試驗環境(38℃、100% R.H.)，監測膨脹量變化。結果顯示，3種模組的初始電流較大，隨通電時間增加電流逐漸降低，以面對線電極模組的折減量最低。線對線陰極陽極電解槽容積小，電解液易蒸發及電滲因素而減少，會影響施加電壓的通電效能。施加的總電量愈高，對平均移出混凝土內的鹼質含量及送入鋰離子有利。面對面及面對線電極模組對離子的傳輸較均勻，線對線電極模組會造成局部區域的離子傳輸無效區。3種電極模組平均殘留的游離態含鹼量由低至高為:面對線、面對面、線對線，效果面對線最佳。平均游離態Li/(Na+K)莫耳比由高至低為: 面對線、線對線、面對面，面對線最佳。以膨脹量觀察，面對線最低，線對線最高。通電過程中陽極使用較高濃度的鋰溶液，對鹼質移出混凝土不利，但對送入鋰離子有利。

This research discusses the practical application simulation of 2-D Accelerated Lithium Migration Technique (ALMT), and the inhibited performance of ASR for different electrode design. To simulate three types of electrode module using in practical application: face-face, face-line, and line-line. To adjust the alkali content of concrete using NaOH to 1.25％ Na2Oeq. After one month curing at room temperature, then proceed the 60 V constant voltage ALMT test for one month. LiNO3 and LiOH．H2O solutions are used as anolyte, and using two kinds of concentration: 0.5 N and 1.0 N. After ALMT testing, the specimens are placed in the environment of ASTM C1293 (38℃, 100% R.H.) and to monitor the variation of expansion. The results show that the initial current of three types of module is high, and then reducing gradually. Face-line module had the lowest reducing rate. The electrolyte volume of line-line module is small, the electrolyte is easy reduce for the reason such as evaporation and electroosmosis, so lowing the performance of electrifying. The higher charge is helpful for removing the alkali out of concrete and driving lithium into concrete. The ion migration is uniform for Face-face and face-line modules, line-line module has some invalid area of ion migration. The average residual amount of alkali for three modules from low to high is face-line, face-face, and line-line, the performance of face-line is best. The average free Li/(Na+K) molar ratio for three modules from high to low is face-line, line-line, and face-face, the performance of face-line is best. From the observing of the expansion amount of specimen, face-line module is lowest and line-line is highest. The higher concentration of anolyte is good for removing alkali out of concrete, but is not good for driving lithium into concrete.
