Evolution of the pozzolanic activity of a thermally treated zeolite
, 2013 Zeolites generally show pozzolanic activity due to their structural characteristics. The utilisation of pozzolans as additions to cements results in added technical advantages of the construction materials. In this study, the pozzolanic activity of a

The Influence of Production Parameters on Pozzolanic Reactivity of Calcined Clays
Nordic Concrete Research, 2018 Calcined clays are gaining increasing interest as future supplementary cementitious materials for the production of blended cements. Besides the mineralogy, the right production conditions can affect the pozzolanic activity of calcined clays.

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.ABSTRACT Workability control of alkali‐activated binders (AABs) remains an obstacle to producing low‐carbon clinkerless ultra‐high‐performance concrete, as their formulation usually necessitates low water‐to‐binder (W/B) ratios, high binder content, and concentrated activator solutions. To address this challenge, a greener and more manageable composite
