Within the scope of study, research on use silica fume (SF), nano (NS) and fly ash (FA) together or separately in production micro concrete is presented. It aimed to examine changes mechanical properties because water air curing mixtures produced using SF, FA, NS. While cement dosage water/binder ratio were chosen as 670 kg/m3 0.53 respectively, amount FA NS was limited 150 total. In samples 40...

This paper investigates how the composition of Portland composite cements affects their chloride-binding properties. Hydrated cement pastes prepared with a reference and containing metakaolin and/or silica fume were exposed to NaCl or CaCl2 solutions. Chloride-binding isotherms determined hydrate assemblage was investigated using TGA, XRD, 27Al NMR, 29Si NMR thermodynamic modelling. Compared pa...
