Abstract

This paper reports the results of chloride binding measurements of GGBS pastes, as well as chloride diffusion and permeability measurements of GGBS concrete mixes. Chloride binding capacity was found to increase with increasing GGBS replacement levels and the chloride exposure concentration. Thermal analysis measurements suggest that much of the improvement in chloride binding is a result of high aluminate levels in GGBS leading to the production of higher quantities of Friedel's salt. When concrete mixes with relatively similar permeabilities are used the chloride binding capacity of the cement matrix becomes a major determining factor in how resistant the concrete is to chloride permeation.
