Dear Dali,

I found one solution here:

Maybe it will be useful.

Thanks Lukasz but I need to describe more details. I think both strength and transport characteristics are linked to the pore structure of the concrete. While in alkali activated slag ion transport can also be related to the pore fluid characterisation which can effect on the binding of different ions before leting them go through concrete or ion friction effects. Now keeping alkali content constant in the system might there be any relation between chloride diffusion and strength?

Dear Dali,

I think that for constant alkali content there may be a relation between chloride diffusion and strength? But, you should try for different alkali contents because this relation may differ. We may suppose that in this situation the higher chloride diffusion will be accompanied with lower strength. But, until now I have not found any proof of it in the literature of the subject.

Hi dali,

I don't think there's strong relationship between the two parameters in AASC, especially chloride ions. The presence of large amount hydroxide will be an obstruction of chloride due to the so called "same ions effect". Moreover, the presence of LDH phase will also provide a shelter for chloride ions in the layer (even though the ions exchange ability of LDHs are follows CO32->SO42->OH->F->Cl-, the concentrations of ions also affect the interlayer ions exchange). Hence, from my point of view, the diffusion of chloride ions show less relationship to the pore structure connectivity of AASC. Also as shown in Qianmin Ma's work, the concentration of chloride on the near-surface of AASC is really high, which are mainly contributed from the above reasons I think.

If you want to build some relationship between transport characteristics and compressive strength of AAS, I think the transport of AIR or water will be more suitable in doing so.
