ABSTRACT

ABSTRACT: In the present paper, the results of an experimental study are presented, where the objective was to provide more information about the effect of granulated blast furnace slag on the resistance of concrete against chloride penetration. In a concrete with a water/binder ratio of 0.40, the portland cement were successively replaced by 40, 60 and 80% of slag, the effect of which was tested by observing the change of both chloride diffusivity and electrical resistivity. For the testing of chloride diffusivity, an accelerated non-steady state migration test method was applied, while the electrical resistivity was tested by use of both the two electrode and the four electrode method.
