• Micromechanical investigation of Portland cement paste (2014, positive): “For the most important and complex phase in Portland cement paste, the C–S–H gel can be divided into inner product (IP) and outer product (OP), and has been comprehensively studied by Richardson [30–35] using SEM and TEM.”
• Chloride Permeability and Microstructure of Portland Cement Mortars Incorporating Nanomaterials (2008, background): “In addition, the needle-shaped ettringite crystals are formed during the early stages of hydration and eventually transform to hexagonalplate crystals of monosulfate hydrate; calcium sulfoaluminates can also include other ingredients such as aluminoferrite to form Al2O3Fe2O3-tri-x SO4 and Al2O3-Fe2O”
• Advances in characterizing and understanding the microstructure of cementitious materials (2019, background): “Although qualitative, transmission electron microscopy (TEM) images indicate the presence of a fine-textured inner product along with a fibrillar/foil-like outer product [48,49].”
• Modelling Elasticity of a Hydrating Cement Paste (2007, positive): “This argument which is mechanical in nature is confirmed by chemical approaches [15–17] and soft X-ray transmission microscopy observations [8].”
• MgO content of slag controls phase evolution and structural changes induced by accelerated carbonation in alkali-activated binders (2014, neutral): “7 ppm in the Al MAS spectrum shows the minor formation of AFm/hydrotalcite type phases, most likely intimately intermixed with the C–A–S–H gel, which is to some extent consistent with the high Al2O3 content present in this slag (Table 1), and also what has been identified in hydrated Portland cement”
• Early hydration and setting of Portland cement monitored by IR, SEM and Vicat techniques (2009, methodology): “Calorimetry is employed to monitor the heat released upon hydration [3–7], whereas X-ray diffraction [8–13], nuclear magnetic resonance [14–16] and Fourier transform infrared spectroscopy, FTIR, are used to”
• Predicting Ca(OH)2 content and chemical shrinkage of hydrating cement pastes using analytical approach (2004, background): “As time passes, silicate chains polymerize [22], but since the present work is limited to early age processes, the C-S-H polymerization is beyond the scope of the study.”
• SCC modification by use of amorphous nano-silica (2014, background): “The main hydration product of cement-based materials, the C–S–H gel, is a nano-structured material [1–4].”
