· JVASP-112604· Ca2Al3O8

Ca₂Al₃O₈ is a calcium aluminate ceramic compound that forms part of the aluminate family of materials commonly encountered in Portland cement chemistry and refractory applications. This phase appears as a constituent in cement clinker and high-alumina refractory systems, where it contributes to binding behavior and thermal stability at elevated temperatures. Engineers encounter this material primarily as a component phase rather than in pure form, valued for its role in improving early strength development and refractoriness in cement-based and refractory products.
