A comparative study of ordinary and mineralised Portland cement clinker from two different production units Part I: Composition and hydration of the clinkers [PDF]

, 2003
Portland cement clinkers from two production units were investigated; Plant 1: ordinary clinker (P1) and clinker mineralised with CaF2+CaSO4 (P1m); Plant 2: ordinary clinker (P2) and two clinkers mineralised with CaF2+CaSO4 (P2m, low SO3 and P2m', high ...

Co‐Calcination of Silicate or Aluminosilicate Network of Clay and Non‐Clay Minerals With NaOH: Physicochemical Insights

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.

Effects of pre-hydration on hydraulic properties on Portland cement and synthetic clinker phases [PDF]

, 2008
The ageing of cements (CEM I 52,5 R and API Oilwell Class G) and also the pure cement clinker minerals (C3S, pure C3A, Na2O-doped C3A, C4AF and calcium sulphate hemihydrate) has been studied at 60% and 85% RH using in-situ XRD, calorimetry, ESEM, XPS and

Enhancing the Reactivity of Dicalcium Silicate Using Aluminum and Sulfur Ions Co‐Doping

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT Belite‐rich cements are a lower‐energy and lower‐CO2 alternative to Portland cements, but the low hydraulic activity of belite remains a major limitation. This study explores the impact of aluminum and sulfur co‐doping on the structure and hydration of synthetic dicalcium silicate (C2S).

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.

Ayrı ve beraber öğütmenin portland kompoze çimentolarının bazı özellikleri üzerine etkileri. [PDF]

, 2009
In the production of cement, to increase the cement/clinker ratio and decrease CO2 emission, the most important alternative is to produce mineral admixture incorporated cements (CEM II-III-IV-V) instead of portland cement (CEM I).
