228-234The present investigation aims to study the
chloride as well as sulphate attack on the composite of 85% SRC and 15% HAC. The
effect of substitution of HAC with silica fume on the aggressive attack was also
studied. The results indicate that the free lime contents decrease with silica fume
and curing time in sulphate as well as chloride solution. The XRD results are in
a good agreement with the compressive strength and chemical analysis. The substitution
of HAC with SF improves the attack of chloride and sulphate ions on cement pastes.
It can be concluded that superplastecizer must be added to the silica fume blended
cements
