The carbonation of metall ic iron is chosen as a model. system due to the ease it offers to understand the mechanisms that drive FeCO 3cementation. The product resulting from such a process can ...
However, the cohesive failure mode was the most frequent in all cementation systems, regardless of the evaluation time, possibly due to the chemical composition and the adhesion mechanism of the cementation systems to the root dentin 5, 6, 8. The dentinal penetrability can be evaluated by confocal laser scanning …
Cement viscosity . Bone cement is available in different levels of viscosity, this ranges for low to high. High-viscosity cement is widely used and has good clinical performance. 34,35 The theoretical advantages of low-viscosity cement are easier handling during cementation due to reduced stickiness, longer polymerization time, improved …
Following nonuniform bio-cementation treatments, specimens achieved calcite contents ranging from 0.5% to 5.3% by mass, shear wave velocity ( Vs) values between 131 and 967 m/s, and mid-depth cone penetration resistances ( qc) ranging between 3.6 and 32.1 MPa. At calcite contents exceeding 5.0%, qc and Vs …

Introduction. Over 370,000 total hip arthroplasties (THAs) are performed annually in the USA [], although only 1–2 out of 10 (14%) utilize cemented femoral stem fixation [].Conversely, such regional pattern is upended in Europe, where 73.1% [] and 56.7% [] rates of cemented femoral stem fixation were described in Sweden and the UK, …
Cyclic voltammetry and linear sweep voltammetry were applied to investigating the reaction mechanism of electrically enhanced cementation of cadmium on a zinc plate. The optimum parameters were a temperature of 35 °C, a cathode-to-anode area ratio of 1:2, an anode current density of 15 A/m 2, an ultrasonic frequency of 40 …
Summary. Kennecott's operating experience with precipitation cones has demonstrated that the application of kinetic principles results in the production of …
The cementation tests were conducted at ambient temperatures, and test data showed reaction temperature variations from 18.5° to 23.5° C. The temperature during the launder test averaged …
The use of cementation in combination with metaphyseal cone augmentation has been described in clinical application in the literature. Indications for this treatment include: massive bone loss comprising a large portion of the femoral condyles or tibial plateaus; and involvement of the collateral ligaments/patellar tendon.
The canals were then enlarged using ProTaper universal system and filled using single cone gutta-percha (GP) andPlus resin sealer. Post space was prepared by removing 10mm of GP from the canal.

Korea University, Seoul, Korea. ABSTRACT: In this study, the cone resistance of cemented sand is measured by per-forming a series of miniature cone penetration tests on the specimens prepared in a calibration chamber. The cementation effect is induced artificially with 5~10% gyp-sum content of sand weight. It is observed from the experimental ...
Abstract. A new method of recovering antimony in hydrochloric acid system by cementation with copper powder was proposed and carried out at laboratory scale. Thermodynamic analysis and cyclic voltammetry test were conducted to study the cementation process. This is a novel antimony removal technology and quite meets the …

A series of cone penetration and bender element tests were performed on sands artificially cemented with gypsum in a calibration chamber to investigate the effect of cementation on the cone tip resistance (q c) and small strain shear modulus (G max) of sand. It was found that both the q c and G max of cemented sand are significantly …
