Hardness in the ITZ of silica sand as aggregate in the concrete is 0.89 GPa and that of limestone as coarse aggregate in concrete is 0.52 GPa. The role of slag in consolidating HCP by better hydration within the ITZ is clearly seen from these experiments. In other words, the presence of the steel slag enhances the chemical reaction in the ...
