Comparison of chloride ingress into silica-fume concrete due to diffusion and absorption

*Basically, a LITERATURE REVIEW of published research papers on diffusion and absorption process of silica-fume concrete related to chloride penetrate through the concrete. Abstract provided as follow:
The use of micro-silica concrete in bridge construction is becoming more
common place. Micro-silica is normally added to concrete at the mixing
stage and reacts during hydration to fill much of the space left empty in
a traditional concrete mix. The material consists of very fine particles
of silica. These are an order of magnitude smaller than cement grains and
aggregate. This not only leads to an increase in the strength of the mix
but also the pores and the cement paste are made more discontinuous, thus
making the hardened concrete better able to resist the ingress of liquids.
Much of the work that has been carried out on chloride ingress into
silica fume concrete has assumed the mechanism is diffusion. But the
wetting and drying of the concrete surface, as happens in bridge
structures, means that capillary suction must also occur. Little research
has been carried out on the absorption properties of silica fume concrete
and the aim of this project is to provide more data on this process and comparison
between these two processes between Pure Porland cement concrete and silica-fume concrete.
