Iron-Cemented Drift in Logan County, North Dakota
… is exposed a well indurated-limonite-goethite cemented glacial drift. The writer believes the origin of the cementing material to be similar to that of most bog-iron ores, and that this cement accumulated during a pre-Wisconsin interglacial age. </p><p>The glacial drift directly overlying the …

Shear behaviour and stiffness of naturally cemented sands
… shear behaviour and stiffness of two naturally cemented sands: a calcarenite with relatively low densities, weak particles and strong bonding and a silica sandstone with high densities, strong particles and weak bonding. Comparative studies were also undertaken on their corresponding …

Study of the properties of cemented carbides from industrial production
Cemented carbides are composite materials formed by high amount of WC bonded by a soft phase, usually Co. They are used in many applications, such as drawing dies, cutting tools and hot rolls due to theirs remarkable properties of high hardness and wear resistance. Mechanical properties are …

Synergistic and Environmental Benefits of Using Cement Kiln Dust With Slag and Fly Ash in Cemented Paste Tailings
… in ordinary Portland cement (CSA Type GU) based cemented paste tailings containing sulphide minerals and have observed secondary gypsum as an ubiquitous phase in such matrices. The secondary gypsum, due to its soft nature and swelling and expansive properties, is principally considered to be the …

Effects of nonhomogeneous cementation in soils on resistance to earthquake effects
… examining the behavior of both naturally cemented and artificially prepared samples. Cemented sands are present in many parts of the world and can be caused by either a variety of cementing agents or by cold welding at points of grain contact. They are generally quite difficult to sample, …

Untersuchungen zum Fräsen mit CVD-diamantbeschichteten Werkzeugen
CVD-diamond coatings on cemented carbide substrates have undergone significant developments in recent years. Former CVD-diamond coated tools failed in metal cutting applications due to severe flaking of the diamond layer. Thus, first industrial applications had been restricted to machining of …
