Impact of calcium aluminate cement with additives on

Calcium aluminate cement (CAC) has been highlighted as a promising alternative for endodontic use aiming at periapical tissue repair. However, its effects on dental pulp cells have been poorly explored. Objective: This study assessed the impact of calcium chloride (CaCl2) and bismuth oxide (Bi2O3) or zinc oxide (ZnO) additives on odontoblast cell response to CAC. Methodology: MDPC-23 cells

Photoalytic performance of calcium aluminate cements

incorporation of the additive in mortars of calcium aluminate cement. Two different CACs were used according to their chemical and mineralogical composition: one of the CAC was a high alumina cement (H-CAC, 70.9% of Al2O3) while the other one was a low alumina cement (L-CAC, 42.0% of Al2O3) with a large amount of ferrite. One batch of the prepared mortars was tested after being subjected to 28

Calcium Aluminate - an overview | ScienceDirect Topics

Calcium aluminate cements are known for their rapid strength gain, especially at low temperatures, superior durability across several such egories and high temperature resistance. Their ability to consume water rapidly during hydration makes them a preferred component in building chemistry appliions as this contributes to construction expediency. CACs are highly versatile materials that

Effect of Polycarboxylate–Ether Admixtures on Calcium

In calcium aluminate cements (CAC), it is recommended to work with low water/cement ratios (for example using superplasticizers admixtures) to avoid the negative effects of metastable hexagonal hydrate conversion to stable cubic ones. The present work studies the compatibility between CAC and three polycarboxylate ether (PCE) admixtures with different structures. The C/E ratio of PCE
