Influence of Aggregate Volume Ratio of Mortar on the Migration of Cations Using the Accelerated Lithium Migration Technique

摘要：

　　This study utilizes mortar specimens,to design 3 different a/c ratios of 2.25,2.75,and 3.25.The aggregate volume ratios (Vf) are 46 %,52 %,and 57 %,respectively,while the w/c ratio is 0.5,and undergoing a 9,12,and 15 A/m2 constant current density Accelerated Lithium Migration Technique after curing for 3 months.Results show that,on specimens applied with the same current density,the time of Li+ to pass through the specimen,and steady state flux and migration coefficient all exhibit a positive linear correlation with Vf.At the same time,the non-steady state migration coefficient for Li+ have a negative linear correlation with Vf.
