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 ...

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.

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

Sulfate optimization in ettringite rich cements by SO3/Al2O3 molar ratio: A comparative study of calcium sulfoaluminate and aluminate cements

Case Studies in Construction Materials
The hydration process of calcium sulfoaluminate (CSA) and aluminate cement (CAC) is influenced by their composition and calcium sulfate sources. Increasing the calcium sulfate content promotes ettringite generation; however, exceeding the optimal ...
