Journal of Marine Science and Technology
This study investigates the effective concrete length and electric field strength during Accelerated Lithium Migration Technique (ALMT) application for the inhibition of the alkali-silica reaction (ASR). Concrete specimens measuring 10 cm in diameter and 5, 7, 9, 11, 14, 17, 20 and 23 cm in length are fabricated. Specimens with 5, 7, and 9 cm in length are applied 9 A/m2 constant current density, and the rest specimens are applied 60 V constant voltage. After the ALMT process, the specimen is cut every 0.5 cm and analyzed its cation content. Experimental results shows that if the aim of ASR inhibition …
