Reaction of water on calcium aluminates
The four calcium aluminates (CaO.Al2O3, 3CaO.5Al2O3, 5CaO.3Al2O3, 3CaO.Al2O2) have been made, and the mechanism of their reacion with water has been studied.

Marginal microleakage of newly synthesized nanostructured materials based on calcium aluminate after application in interradicular perforations [PDF]
Introduction Marginal seal or adequate marginal adaptation of material along the cavity walls should be able to prevent leakage of tissue fluid and consequently bacterial microleakage, terefore, it is considered as significant factor for long term ...

Liquid Inclusion Collision and Agglomeration in Calcium-Treated Aluminum-Killed Steel
This work addresses conflicting results in the literature regarding liquid inclusion agglomeration. To assess whether liquid calcium aluminates do agglomerate in liquid steel, laboratory experiments were performed: melting electrolytic iron, deoxidizing ...

Structure and non-stoichiometry of calcium aluminates [PDF]
Abstract Lattice imaging of reaction-sintered ceramic compounds in the CaO‒Al2O3 system showed 00.1 syntactic intergrowths in the matrix CaO. 6Al2O3 phase. The structure of these intergrowths could be interpreted in terms of the concepts used to describe various magnetoplumbite phases (Braun 1957).

Prediction of Inclusion Types From BSE Images: RF vs. CNN
The analysis of non-metallic inclusions is crucial for the assessment of steel properties. Scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS) is one of the most prominent methods for inclusion analysis.

Rehydration of katoite as a layered double hydroxide: an in situ study
Calcium aluminate layered double hydroxides (Ca-Al LDHs) constitute a considerable part of cementitious waste fines. Although cementitious waste fines have proven to be recyclable by thermal treatment at moderate temperatures (400–700 °C), understanding ...
