Calcium Aluminate Cement and Refractory Castable
Transactions of the Indian Ceramic Society, 1993Monocalcium aluminate and calcium dialuminate were prepared by heating different mixes of CaO and Al2O3, at 1400° and 1600°C respectively, evidence of which was found by X-ray diffraction study. Castables were made from the mixes of CA and CA2 in specific proportions, hydrated by keeping immersed in water and subsequently tested for strength.Hydrated ...

Osteogenic cell response to calcium aluminate‐based cement
International Endodontic Journal, 2016AbstractAimTo evaluate the effect of a calcium aluminate‐based cement (CAC+) on the development of the osteogenic phenotype in vitro.MethodologyRat calvaria‐derived cells were grown on Thermanox® coverslips for 24 h and then exposed to either samples (4‐h set) of CAC+ or mineral trioxide aggregate (MTA) placed on Transwell® inserts for periods of up to

Hydroxyapatite formation on surface of calcium aluminate cements
Advances in Applied Ceramics, 2011AbstractAbstractIn this study, we report the formation and characterisation of a calcium aluminate cement for potential application as a hard tissue replacement. Phase pure monocalcium aluminate powder was synthesised using the Pechini technique, using a relatively low temperature (1000°C) and sintering time (3 h).

Properties of hot-pressed calcium aluminate cements
Cement and Concrete Research, 1975Abstract Simultaneous heating and pressing techniques were applied to ordinary calcium aluminate cements (40% Al2O3) and high aluminate (72%) cement. The compressive strength of the former, when hot pressed at 50, 000 psi, 250°C, 1 2 hr. is 51, 000 psi, while the latter is 45, 000 psi.

Calcium aluminate cement hydration
2008Iako je hidratacija aluminatnog cementa (AC) proces od temeljne industrijske i komercijalne važnosti, kemijske reakcije pri hidrataciji nedovoljno su razjašnjene. Znanstvena istraživanja s područja malobrojna su u usporedbi s istraživanjima na portland cementu.

Kinetic modeling of calcium aluminate cement hydration
Chemical Engineering Science, 2010The hydration of iron-rich calcium aluminate cement (CAC) has been investigated by differential calorimeter and quantitative powder X-ray diffraction (QXRD). A simplified stoichiometric model of early age CAC hydration based on reaction schemes of the principal mineral monocalcium aluminate was employed. The CAC characteristic feature of retardation of
