N2 - With the current paper three nano-Montmorillonites (nMt) are applied in cement nanohybrids; an organomodified nMt dispersion, nC2, an inorganic nMt dispersion, nC3 and an organomodified powder, nC4. nC4 is fully characterized in this paper (X-ray diffraction, Scanning electron microscopy/X-ray energy dispersive spectroscopy and thermal gravimetric analysis/differential thermogravimetry. Consecutively a ternary non pozzolanic combination of fibre-cement nanohybrids [60% Portland cement (PC) and 40% limestone (LS)] was investigated in terms of flexural strength, thermal properties, density, porosity, water impermeability. Flexural strength was improved after day 28 particularly with the addition of the inorganic nMt dispersion. There was no change in density or enhancement in pozzolanic reactions for the powder nMt. Mercury Intrusion Porosimetry showed that the pore related parameters were increased. This can be attributed to mixing effects and the presence of fibres. Water impermeability tests yielded ambiguous results. Clearly, novel manufacturing processes of cement nanohybrids must be developed to eliminate mixing issues recorded in this research.
