The Phases and Structure of Calcium Aluminate Cements (CACs)

11/9/2002· The main hydraulic mineral in CAC is calcium mono-aluminate (CA). The hydration of CA contributes to the high initial strength of CACs. CA is a monoclinic phase and pseudo-hexagonal, and its space group is P21/n, Z = 12, and D x = 2.945 g/cm 3. Moreover, it reseles the structure of β-tridymite with an endless 3D framework of AlO 4 tetrahedra

Bioactivity of calcium aluminate endodontic cement

Introduction: Calcium aluminate endodontic cement (CAEC) developed for use in root canal therapy has been produced with additives that improve handling properties and provide higher mechanical strength than mineral trioxide aggregate (MTA) according to prior studies.

High Alumina Cement - Manufacturing, Pros & Cons

High Alumina Cement (HAC) is also known as calcium aluminate cement (CAC) or aluminous cement, is composed of calcium aluminates. High Alumina Cement was first manufactured by Lafarge, the cement producer, and became available in the UK in 1925. It has good resistance to be resistant to chemical attacks which are required in marine construction
