TLDR
In this article, a scheme of phase balances was proposed to calculate the mineralogical balances of a hydrated cement paste with greater accuracy than hitherto practicable, and experimentally-determined phase relationships were depicted at 25 deg. C.About:

Microstructural developments of limestone calcined clay cement (LC3) pastes after long-term (3 years) hydration
Franco Zunino,Karen Scrivener +1 more
TL;DR: In this paper , a detailed study of phase assemblage, porosity evolution and microstructural development was conducted on LC3 samples hydrated up to 3 years and compared to 90 days specimens.

Effect of Friedel’s salt on strength enhancement of stabilized chloride saline soil
TL;DR: In this paper, a new hydration product of calcium aluminate chloride hydrate, also known as Friedel's salt, appeared in the PC+CH-stabilized chloride saline soils.

Evaluation of chloride transport in blended cement mortars containing coal mining waste
Laura Caneda-Martínez,Moisés Frías,César Medina,Mª Isabel Sánchez de Rojas,Nuria Rebolledo,J. Sanchez +5 more
TL;DR: In this article, the effect of coal mining waste (CMW) on the chloride permeability of blended cements in amounts from 10 to 50% was assessed by salt ponding test.

Effect of coupled B/Na and B/Ba doping on hydraulic properties of belite-ye’elimite-ferrite cement
Chen Li,Mengxue Wu,Wu Yao +2 more
TL;DR: X-ray diffractometry (XRD) showed that coupled B/Na and B/Ba doping improved the compressive strength compared with the cement paste without dopants as mentioned in this paper.
Hydration and dimensional stability of calcium aluminate cement based systems
TL;DR: In this paper, the authors studied the properties of CACs with and without supplementary cementitious materials (SCM) from the first hours up to two years of hydration and showed that the calcium sulfate reacts with CAC and only when sulfate is exhausted does slag or limestone react with aluminate phases.

The Role of Calcium Carbonate in Cement Hydration
TL;DR: In this paper, it is shown by experiment and calculation that much, if not all, of this calcite is reactive and affects the distribution of lime, alumina and sulfate and thereby alters the mineralogy of hydrated cement pastes.

Thermodynamic modelling of the hydration of Portland cement
TL;DR: In this paper, a thermodynamic model is developed and applied to calculate the composition of the pore solution and the hydrate assemblage during the hydration of an OPC.

Thermodynamic investigation of the CaOAl2O3CaSO4H2O system at 25°C and the influence of Na2O
D. Damidot,F.P. Glasser +1 more
TL;DR: In this article, the CaOAl2O3CaSO4H2O system at 25°C has been investigated by calculations on the equilibrium solubility surfaces of AH3, C3AH6, CH, C 6 A S 3 H x, C 4 A S H x and gypsum.
