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.

Modifications in hydration kinetics and characteristics of calcium aluminate cement upon blending with calcium sulfoaluminate cement

Construction and Building Materials, 2022
The present study explores the modifications in hydration kinetics and characteristics of calcium aluminate cement (CAC) upon blending with calcium sulfoaluminate (CSA) cement. CAC was replaced with CSA cement at 0, 30, 50, 70, or 100 wt%.

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 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 ...

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 ...

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).

Calcium Aluminate Cement and Refractory Castable

Transactions of the Indian Ceramic Society, 1993
Monocalcium 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, 2016
AbstractAimTo 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
