Effect of the Interfacial Transition Zone on the Migration Behavior of Cations under the Accelerated Lithium Migration Technique

Abstract:

This paper researches the effect of the interfacial transition zone (ITZ) on the migration behavior of cations under the Accelerated Lithium Migration Technique (ALMT). Cylindrical mortars with different aggregate volume fractions (V_f) and w/c=0.5 were used. The result shows that when V_f ≤ 20 %, the Li⁺ steady state migration coefficient (D_s) is influenced by the dilution and tortuosity effects of the aggregate. The combined effect of ITZ and percolation occurs at V_f = 30 %, and the effects increase with the increase in V_f. Based on the experimental and regression analysis results, when the assumed thickness of ITZ = 20 μm, the approximate D_s of ITZ and percolated ITZ are 46.4 and 52.6 times the matrix migration coefficient.
