New cements for the 21st century: The pursuit of an alternative to Portland cement
TLDR
Aluminosilicate-based alkaline cements have been classified into five categories as discussed by the authors, and the key advances made in the understanding of synthetic gels are discussed, which ultimately finds hybrid cements to be technologically viable materials for contemporary construction.About:

A review of the multi-component utilisation of coal fly ash
Robert Blissett,Neil A. Rowson +1 more
TL;DR: In this paper, the potential applications for coal fly ash as a raw material were reviewed. And the authors found that there is significant potential for the increased utilisation of coal fly-ash both in its raw and refined state.
Journal ArticleDOI
Advances in understanding alkali-activated materials
TL;DR: Alkali activation is a highly active and rapidly developing field of activity in the global research and development community as discussed by the authors, and commercial-scale deployment of alkali-activated cements and concretes is now proceeding rapidly in multiple nations.

The Chemistry of Silica: Solubility, Polymerization, Colloid and Surface Properties and Biochemistry of Silica
TL;DR: Weber and van Olphen as discussed by the authors provide valuable guidance in research and design efforts by giving a clear understanding of principles and concepts of colloid chemistry as applied to clay systems, including surface characterization and adsorption mechanisms; recent results in the area of clay-organic interaction-the intercalation and intersalation of kaolinite minerals; and increased attention to the possible role of clays in biological evolution.
