This study is part of numerical simulations performed on an in situ heating test conducted by the French National Radioactive Waste Management Agency (Andra) at Meuse/Haute-Marne Underground Research Laboratory (URL) to thermal-hydromechanical behavior host Callovo-Oxfordian COx claystone quasi real conditions, through international research project DECOVALEX. The emphasis put pore pressure inc...

calcareous nannofossil assemblages of the boundary paleocene-eocene deposits (pabdeh formation) of the zagros, dezful embayment-mansouri oilfield have been studied in detail. it consists of shale and grey marlstone with inter layers of calcareous argillites and marly claystone. we present a study focused on changes in calcareous nannofossils of the pabdeh formation during the paleocene/eocene b...

The coupled Thermo-Hydro-Mechanical (THM) behavior of the Callovo-Oxfordian claystone (COx) is great importance for design and safety calculations high-level radioactive waste disposal project in this potential host rock France. heat emitted by causes a pore pressure increase within surrounding essentially due to differential thermal expansion water solid skeleton. low permeability COx its rela...

The present study focused on investigating the differences in properties between calcined and milled aluminosilicates with different particle size distributions. Two types of clay, i.e., kaolin kaolinitic claystone, were subjected to calcination at 750 °C, subsequent milling obtain fractions distinct These then combined a potassium alkaline activator quartz sand 50:50 weight ratio form geopolym...
