Applied Research, Volume 5, Issue 4, August 2026.ABSTRACT Eco‐friendly construction practices have emerged as a cornerstone of modern development. Due to the substantial carbon emissions from cement production, there is a growing demand for supplementary cementitious materials. This study investigated the synergistic effects of two different wastes, silica‐rich rice husk ash (RHA) and calcium‐rich ...

Pozzolanic Activity Diagnostics of Fly Ash for Portland Cement
Chemistry & Chemical Technology, 2016 The work deals with the analysis and evaluation of different methods of pozzolanic activity determination in order to rationally use ash in cement. The most optimum diagnostic method has been suggested. The possibility of increasing fluidal fly ash activity has been established using the synthetic nanosilica.

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.Effects of co‐calcination with alkali hydroxide on pure clay minerals (kaolinite, montmorillonite) and typical impure minerals (quartz, feldspar) are presented. Co‐calcining montmorillonite and quartz with sodium hydroxide improves their reactivity. Co‐calcining kaolinite with sodium hydroxide reduces its reactivity.
