The Influence of Chemical Activity Models on the Description of Ion Transport through Micro-Structured Cementitious Materials

The significance of ion activity in transport through a porous concrete material sample with steel rebar in its center and bathing solution is presented. For the first time, different conventions and models of ion activity are compared in their significance and influence on the ion fluxes. The study...
