The increase in the UCS was most apparent in the 2% cemented specimen wherein the UCS increased more than three times as the fiber ratio increased up to 1%.
In summary, teeth that are restored with an indirect glass-ceramic restoration, with respect to in vitro fracture strength of posterior adhesively cemented specimen, exhibit higher fracture strength with adhesive cements.
An innovative apparatus has been developed in this study to cure and test oil well cement specimens under simulated down-hole conditions with high temperature and high pressure.
In this study, a series of the thick-walled hollow cylinder (TWHC) laboratory tests was conducted on synthetic poorly cemented sand specimens in which the applied stresses were at levels of generating breakout on the borehole wall.
To investigate the influence of different factors on the initiation of particle debonding at the borehole wall, a series of new laboratory tests was designed and performed on synthetic poorly cemented sand specimens.
In this study a series of solid and thick-walled hollow cylinder (TWHC) laboratory tests was performed on synthetic poorly cemented sand specimens.
Plug tests conducted on shale and cement specimens highlight the importance of hairline cracks in otherwise intact small-pore materials.
Furthermore, in comparison with reference specimens (i.e. specimens with no cement) and type I cement specimens, I (PM) cement had the mean fatigue behavior.
