Recycling Of Auriferous Ore Flotation Tailings In Slag-alkaline Cement [PDF]

, 2016
Research analysis aimed at stabilizing processes in industrial waste and other, similar hazardous ion containing materials, shows that these materials can be successfully stabilized, if they are bound as a mineral component in cement.

Fatigue behaviour of root filled teeth: The role of endodontic sealers and restorative techniques

European Journal of Oral Sciences, EarlyView.
Abstract This in vitro study aimed to evaluate the fatigue behaviour of root canal treated teeth, filled with either AH Plus Jet (AHP) or AH Plus Bioceramic Sealer (AHPB) and rehabilitated with either mesio‐occlusal‐distal (MOD) restorations (direct resin composite) or endocrowns (indirect resin composite).

Microstructural changes induced by CO2 exposure in alkali-activated slag/metakaolin pastes

Frontiers in Materials, 2016
The structural changes induced by accelerated carbonation in alkali-activated slag/ metakaolin (MK) cements were determined. The specimens were carbonated for 540 h in an environmental chamber with a CO2 concentration of 1.0 ± 0.2%, a temperature of 20 ±

Physicochemical and remineralisation properties of calcium silicate and glass ionomer cements applied in simulated caries‐affected dentine

European Journal of Oral Sciences, EarlyView.
Abstract Calcium silicate‐based and glass ionomer cements are often used in caries‐affected dentine. This study investigated the remineralising and physicochemical properties of two calcium silicates and a glass ionomer cement. Human molars with Class I cavities were subjected to pH cycling to simulate caries lesions.

The microstructure, composition, physical properties, and bioactivity of calcium silicate cement prototypes for vital pulp therapies

Journal of Applied Biomaterials & Functional Materials
Hydraulic calcium silicate cements (HCSCs) are valuable for various dental procedures. However, several reports document inherent limitations and complaints about their high costs, hindering accessibility in low—and middle-income countries.

Development of CCMb: A Low‐Mg Calcite Reference Material for In Situ Measurement of δ18O, δ13C and Selected Trace Elements

Geostandards and Geoanalytical Research, EarlyView.
Key Points Low‐Mg calcite RM developed for in situ microanalysis applications in palaeoclimatology (δ18O, δ13C; Mg, Sr m/m). New data for calcite CRM IAEA‐603 (δ18O, δ13C by SIMS and GS‐IRMS; Mg m/m). No detectable IMF effect of Mg on SIMS δ18O determinations for mass fractions < 3650 μg g‐1.

Exploring a new Portland cement-free calcium silicate cement —Part 1: Synthesis of dicalcium and tricalcium silicate

Dental Materials Journal
Mineral trioxide aggregate cement is an excellent pulp-capping material; however, its base Portland cement contains highly toxic elements and is expensive. This study aimed to explore the possibility of using calcium silicate cement without Portland cement.
