Investigation of using limestone calcined clay cement (LC3) in engineered cementitious composites: The effect of propylene fibers and the curing system
TL;DR: In this paper, polypropylene (PP) fibers were mixed into limestone calcined clay cement-based materials to make new low-carbon ECCs, and a compressive constitutive model of the composites was deduced and obtained.
Influence of ferrite phase in alite-calcium sulfoaluminate cements
TL;DR: In this paper, a hybrid mixture of Ordinary Portland Cement (OPC) and calcium sulfoaluminate (CSAC) clinker phases was used to produce high-iron alite-calcium sulfo aluminate-ferrite cements.

Impact of the coupled substitution of CaCO3 and CaSO4·2H2O on chloride binding behavior in hydrated C3A pastes
Guo Minglei,Jia Xiao,Jialei Wang +2 more
TL;DR: In this paper, the impact of CaCO3 and CaSO4·2H2O on chloride binding in hydrated blended C3A pastes was investigated, and the results showed that the exposure of the CA pastes to NaCl solutions caused an increase of pH as a result of the chloride binding by the AFm 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.
