要旨 The ionic diffusivity of lithium and sodium compounds was investigated by diffusion cell test. The diffusion coefficients of Na+ ions were 10 times more than Li+ ions. This is an indication of lithium ions is better adsorbed into the hydration products compared with others, especially Li2SiO3. This finding is backed-up by results of post-analysis such as DSC and XRD. The results of mortar bar tests were adding confidence to the mitigation effects of lithium on ASR of concrete. Expansions only observed for mortar bars immersed in sodium compounds solution, especially in 0.5 mol/L Na2SiO3.
