TLDR
In this article, the conditions that must be met for MIP measurements to provide valid estimates of the pore size distribution of porous solids are reviewed and evidence is presented indicating that these conditions are not satisfied in cement-based systems.About:

Changes in portlandite morphology with solvent composition: Atomistic simulations and experiment
TL;DR: In this article, a new analysis tool was developed to quantify the experimentally observed changes in morphology of portlandite, allowing the calculation of the relative surface energies of the crystal facets.

Backscattered electron imaging of cementitious microstructures: Understanding and quantification
TL;DR: In this article, the general microstructural features of hydrated cement pastes are described and the possibilities to quantify backscattered electron imaging images of polished surfaces are described. And an example of the potential for BSE images to study concrete durability is given.

Technical and commercial progress in the adoption of geopolymer cement
TL;DR: In the absence of an in-service track record comparable in scale and longevity to Portland cement, research is essential to validate durability testing methodology and improve geopolymer cement technology Colloid and interface science, gel chemistry, phase formation, reaction kinetics, transport phenomena, comminution, particle packing and rheology.

Porosity, pore size distribution and in situ strength of concrete
TL;DR: In this paper, the in situ strength of concrete was determined through compression test of cores drilled out from laboratory cast beams, and the apparent porosity and pore size distribution of the same concrete were determined through mercury intrusion porosimetry, performed on small-drilled cores.

Mercury porosimetry of hardened cement pastes
Raymond A. Cook,Kenneth C. Hover +1 more
TL;DR: In this article, the porosimetry was performed on 92 hardened cement paste specimens of water/cement (w/c) ratios 0.3, 0.4, 0 4, 0 5, 0 6, 0 7, 14, 28, and 56 days.

Hydration kinetics, change of relative humidity, and autogenous shrinkage of ultra-high-strength concrete
TL;DR: In this paper, the shrinkage and creep of compact reinforced composite (CRC) is investigated and a relationship between autogenous shrinkage with self-desiccation is established and discussed.

Sulphate Resistance of Metakaolin Mortar
Jamal Khatib,S. Wild +1 more
TL;DR: In this article, the partial substitution of cement with metakaolin (MK) is investigated in terms of resistance of MK mortar to sodium sulphate (Na2SO4) solution, and results on strength, porosity, pore size distribution, and calcium hydroxide (CH) contents are also reported.

Image-based characterization of cement pore structure using wood’s metal intrusion
TL;DR: In this paper, Wood's metal solidifies within the pore structure of the sample, which allows it to be sectioned and observed in the scanning electron microscopy, and the sample can be analyzed both qualitatively and quantitatively by applying image analysis techniques.
