Effect of silica fume additions on the hydration behaviour of calcium aluminates
, 1997 In the recent refractory castables technology, the calcium aluminate cement is being replaced in increasing proportion by very fine matrix components, such as silica fume and colloidal alumina.

Calcium Aluminates Synthesis, Characterization, and Hydration Behavior [PDF]
, 1984 The hydration behavior of the calcium aluminates as a function of the glass content, the curing temperature, and the water-solid ratio was investigated. In order to keep them from influencing the results, the free-lime content and the surface area of all

In Situ X‐Ray Diffraction Study of a Microwave‐Based Hydrothermal Synthesis of Mayenite Ca12Al14O33
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.Microwave‐assisted hydrothermal synthesis enables rapid transformation of aluminium‐ and calcium‐hydroxide into mayenite with high surface area. Optimised synthesis conditions comprise a microwave step at 80°C for 5 min followed by calcination at 800°C. The reactions during calcination were studied via in situ XRD measurements.

Hydration of calcium aluminates and calcium sulfoaluminate studied by Raman spectroscopy
, 2014 Raman spectroscopy has been used to follow the hydration of the main calcium aluminate phases present in calcium aluminate cement (CAC) and calcium sulfoaluminate cement (CSA) clinkers, i.e. C3A, CA, C 12A7, CA2, C4AF and C 4A3SÌ„.

Journal of Forensic Sciences, EarlyView.Abstract Forensic ballistics is essential in analyzing evidence from firearm use in criminal investigations, with gunshot residue (GSR) detection providing key information about the firearm and shooting conditions. Traditional methods like spectroscopy and scanning electron microscopy (SEM) have limitations in sensitivity, cost, and accessibility ...

The Hydration Products of a Refractory Calcium Aluminate Cement at Low Temperatures [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2007 Calcium aluminates (CA) are the most important hydraulically setting cements used for preparing refractory castables, because they develop high strength at very early ages after placements.
