Phase formation in the CaO–Al2O3–ZnO system as an analogue to CaO–Al2O3–MgO in spinel containing refractories

Journal of the American Ceramic Society, Volume 108, Issue 5, May 2025.
Abstract Recently, gahnite (ZnAl2O4) is gaining attraction as a potential refractory ceramic because of the similarity of its structure and properties with those of magnesium aluminate (MgAl2O4) spinel refractories. Formation of MgO and hibonite solid solution (CaMgxAl12−xO19−0.5x; 0 ≤ x ≤ 0.18), CAM‐I (Ca2Mg2−3xAl28+2xO46 (0 ≤ x ≤ 0.3), and CAM‐II ...

Calcium aluminate cement in castable alumina: from hydrate bonding to the in situ formation of calcium hexaluminate [PDF]

, 2021
Calcium hexaluminate (CA6) is an intrinsically densification-resistant material, therefore, its porous structures are key materials for applications as high-temperature thermal insulators.

Monocarboluminate: Sorption dependence of thermal, elastic, and transport properties

Journal of the American Ceramic Society, Volume 108, Issue 3, March 2025.
Abstract Monocarboaluminate is the major phase in calcium aluminate cements and is the main AFm phase in modern cement that incorporates limestone additions, including limestone calcined clay cement. This study reports thermal, elastic, and transport properties of monocarboaluminate obtained from molecular simulations.

New approach of recycling vanadium‐bearing slags as a binder in high‐alumina refractory castables application

International Journal of Ceramic Engineering &Science, Volume 7, Issue 1, January 2025.
This study investigated the use of vanadium‐bearing slag as an alternative to calcium aluminate cement in high‐alumina refractory castables, with the aim to support decarbonization by reducing reliance on natural raw materials. Abstract Handling the massive quantities of by‐products from metallurgical processes has become a major concern in recent ...

Statistical Analysis of Expansive Soil Stabilized With Calcium Carbide Residue and Rice Husk Ash Using Response Surface Methodology

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Expansive soils present significant engineering challenges due to their swelling, shrinkage, low strength, and limited bearing capacity, particularly under moisture variations. To address these issues, sustainable soil stabilization techniques using industrial byproducts have gained attention. Among them, rice husk ash (RHA) and calcium carbide residue
