Premixed calcium silicate cement for endodontic applications
Calcium silicate-based materials (also called MTA) are increasingly being used in endodontic applications. However, the handling properties of MTA are not optimal when it comes to injectability and cohesion. Premixing the cements using glycerol avoids these issues. However, there is a lack of data on the effect of common cement variables on important properties of premixed cements for endodonti...
متن کاملThe Hydration Products of a Refractory Calcium Aluminate Cement at Low Temperatures
Calcium aluminates (CA) are the most important hydraulically setting cements used for preparing refractory castables, because they develop high strength at very early ages after placements. The anhydrous phases of this kind of cements are CA, CA2 and traces of C12A7 and alpha-alumina. The major hydraulic phase in all of the CA cements including ciment fondu...
متن کاملThe Hydration Products of a Refractory Calcium Aluminate Cement at Intermediate Temperatures
The major hydraulic phase in all the calcium aluminate cements including ciment fondue is CA (CaAl2O4). Once hydrated, it starts to form the hexagonal crystals of CAH10 and C2AH8 that depending on the time and temperature of hydration convert to the cubic crystals of C3AH6 and AH3. The nature, sequence, ...
متن کاملEffects of High Temperature on Carbonated Calcium Silicate Cement (CSC) and Ordinary Portland Cement (OPC) Paste
This paper presents a comparative study on the effects of high temperature (~500°C) on carbonated calcium silicate-based cement (CSC), hydrated ordinary Portland cement (OPC), and hydrated OPC with 20% fly ash (FA) paste samples. The CSC is primarily composed of calcium–silicate minerals with different calcium to silica atomic ratios, such as wollastonite, rankinite, and pseudowollastonite. The...
متن کاملHydration water and microstructure in calcium silicate and aluminate hydrates
Understanding the state of the hydration water and the microstructure development in a cement paste is likely to be the key for the improvement of its ultimate strength and durability. In order to distinguish and characterize the reacted and unreacted water, the single-particle dynamics of water molecules in hydrated calcium silicates (C3S, C2S) and aluminates (C3A, C4AF) were studied by quasi-...
