Pore structure analysis of hardened cement mortars containing silica fume and different nano-powders

In this article, the 56-day pore structures of the cement mortars produced by the addition of silica fume and nano-SiO2 (NS), nano-Al2O3 (NA) and nano-Fe2O3 (NE) powders in singular, binary or ternary combinations at 3 different proportions (0.5%, 1.25% and 2.5%) of the binder content were investigated through MIP and BET analyses. The compressive strengths and capillary water absorptions of produced mortars were also determined in order to investigate the effects of changes in pore structure on these properties.
