Mechanisms of cement hydration
Jeffrey W. Bullard,Hamlin M. Jennings,Richard A. Livingston,André Nonat,George W. Scherer,Jeffrey Schweitzer,Karen Scrivener,Jeffrey J. Thomas +7 more
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.

Advances in alternative cementitious binders
TL;DR: In this paper, four promising alternative binders available as alternatives to Portland cement are discussed, namely calcium aluminate cement, calcium sulfoaluminate cements, alkali-activated binders, and supersulfated cements.

The coexistence of geopolymeric gel and calcium silicate hydrate at the early stage of alkaline activation
TL;DR: In this paper, the effects of ground granulated blast furnace slag (GGBFS) on the microstructure and mechanical properties of metakaolin (MK) based geopolymers were studied.

A model for the microstructure of calcium silicate hydrate in cement paste
TL;DR: In this paper, a model for the structure of calcium silicate hydrate (C-S-H) as it is formed during the hydration of Portland cement is proposed, which is a simplified representation of the microstructure within the size range of about 1 to 100 nm.

Innovation in use and research on cementitious material
TL;DR: In this paper, the authors discuss the factors that have enabled these developments and ongoing needs in these areas and discuss the importance of sustainability as the major driver for future innovations and prospects for development of new cementitious materials with lower environmental impact.
