Supercritical carbonation of calcium aluminate cement

open access: yesCement and Concrete Research, 2008
The microstructural changes occurring during supercritical carbonation (scCO2) of calcium aluminate cement (CAC) and changes to its strength have been investigated. Cylindrical specimens of CAC cured at different temperatures were prepared and then subjected to scCO2.

Biocompatibility of New Calcium Aluminate Cement (EndoBinder)

Journal of Endodontics, 2012
The purpose of this study was to evaluate the biocompatibility of calcium aluminate cement (EndoBinder) in subcutaneous tissue of rats.Fifteen rats, weighing 300 g, were separated into 3 groups (n = 5) in accordance with the time of death (7, 21, 42 days).

Phosphate modified calcium aluminate cement for radioactive waste encapsulation [PDF]

open access: yesAdvances in Applied Ceramics, 2013
The present study is part of a wider investigation to develop an alternative cementing system for the encapsulation of problematic low and intermediate level radioactive waste. It has been suggested that alternative cementing systems, with lower internal

Bioactivity of Calcium Aluminate Endodontic Cement

Journal of Endodontics, 2013
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.

Calcium Aluminate Cement and Porcelain

Advanced Materials Research, 2014
Porcelain is a traditional ceramic material, which is manufactured for centuries from a mixture of kaolin - quartz - feldspar. Replacement of kaolin for calcium aluminate cement can be achieved primarily increases strength of fired body, reduces the coefficient of linear thermal expansion, increases the whiteness of the fired body and increases of ...

Calcium silicate and calcium aluminate cements for dentistry reviewed

Journal of the American Ceramic Society, 2021
Abstract Calcium silicate cements were identified as excellent materials for dentistry, particularly for dental procedures contacting the dental pulp or root system. Both calcium silicate and calcium aluminate cements cause the biomineralization (precipitation of hydroxyapatite [HA] phenomena and shield dental tissues from the ...

Porosity–strength relation in calcium aluminate cement pastes

Cement and Concrete Research, 2003
The compressive strength and the volume porosity of calcium aluminate cement pastes have been studied in order to connect their relationship. The influence of mass fraction of lithium carbonate on compressive strength and porosity of calcium aluminate cement (CAC) has been investigated at different water– cement (w/c) ratios.

Characterisation of calcium aluminate cement hydration

2022
After water, cement is the second most widely used substance in the world and the largest manufactured product by mass. Calcium aluminate cement (CAC) is a special cement used for high- performance applications (resistance to chemical attack, high early strength, refractory use, abrasion resistance, and/or use at low ambient temperatures).
