Assessment of Pozzolanic Activity Using Methods Based on the Measurement of Electrical Conductivity of Suspensions of Portland Cement and Pozzolan [PDF]

Materials, 2014
The use of methods based on measuring electrical conductivity to assess pozzolanic activity has recently been used primarily in aqueous suspensions of pozzolan: calcium hydroxide. However, the use of similar methods in suspensions of cement with pozzolans has not been widely studied.

In Situ Raman Spectroscopy of a Silica Gel‐Templated Hydration Pathway in CO2‐Activated Cement

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT This study investigates early‐age carbonate mineralization in cementitious systems using in situ Raman microspectroscopy. In the presence of dissolved CO2, clinker phases undergo accelerated dissolution, decomposing to form various calcium carbonate polymorphs and a transient amorphous silica gel network.
