... the chloride binding capacity of mortar than Na⁺. This is because Ca²⁺ promotes the positive potential of the C–S–H gel in the mortar and Mg²⁺ facilitates the generation of a solid solution of Friedel’s salts and AFm in the mortar. The addition of MK in mortar improves...

... cement paste C-S-H performance characterisation printability/rheology As already mentioned, the print material needs to meet ‘dual-rheology’ requirements at the same time – that is, pumpability and extrudability, along with buildability and open-time requirements (Figure 3) (Ishida and Nakada...

... hydration was slowed. Conversely, when the MASR was too low, this enabled large amounts of AFt to occupy the space where calcium silicate hydrate (C-S-H) gels were formed, resulting in decalcification of the C-S-H gels. 17 09 2023 06 12 2023 Emerald Publishing Limited: All rights reserved...

... by predicting the sorption isotherm, the drying shrinkage and the self-desiccation of cement paste directly from the evolution of its microstructure. A simple hydration model was developed to predict the microstructure of Portland cement pastes, as well as the nanostructure of calcium silicate hydrate (C-S-H...

... to sorption of the organic solvent in the C–S–H gel. This organic solvent is not removed by normal drying process such as oven drying or low-vacuum drying (Taylor and Turner, 1987). Currently, it is not recommended to grind cement pastes very finely because long exposure times and increased fineness...
