TL;DR: The current state of knowledge of cement hydration mechanisms is reviewed, including the origin of the period of slow reaction in alite and cement, the nature of the acceleration period, the role of calcium sulfate in modifying the reaction rate of tricalcium aluminate, the interactions of silicates and aluminates, and the kinetics of the deceleration period as mentioned in this paper.
TL;DR: In this article, the applicability of the tobermorite-jennite (T/J) and T/CH viewpoints for the nanostructure of C-S-H present in real cement pastes is discussed.
TL;DR: In this article, the authors employed Diffuse Reflectance Infrared DR-FTIR spectroscopy to monitor chemical transformations in pastes of Portland limestone cement and concluded that the setting is caused by interparticle coalescence of C-S-H.
TL;DR: In this article, the authors reviewed the hydration mechanisms of alite and Portland cement and found that the main heat evolution peak hydration is dominated by the growth of outer C-S-H with a spiky or needle-like morphology.
TL;DR: In this paper, the properties of Portland cements (C3S and alite, C2S, C3A, C4AF) were measured at the microscopic scale by nanoindentation and at the macroscopic scale by the resonance frequencies technique.
