The Cobourg limestone is a heterogeneous argillaceous rock consisting of lighter nodular regions of calcite and dolomite, interspersed with darker regions composed of calcite, dolomite, quartz and ...

The shaft capacity of hard limestone obtained from the load test at the final loading step was 1.4 times larger than the shaft capacity that is obtained using the highest value of limit unit shaft ...

The word Argil means clay. Hence, the rocks in which clay content is predominant are called argillaceous rocks. These rocks are soft in nature and with the presence of water they can be crumbled easily. In the dry state, these rocks can be crushed easily because of their brittleness. Shale, slate, laterite, etc. are some of the argillaceous rocks.

It is indispensable to give a simple historical review of the progress realized in the study of the clay geology and especially in the understanding of the genesis of clay minerals. This history is intimately linked with that of clay mineralogy which perfects the...

The mobilization of side resistance has a significant effect on load-transfer characteristics and the ultimate bearing capacity of rock-socketed piles. A good understanding of the shear mechanism of a concrete–rock interface has a critical part in analytical load-transfer solutions of rock-socketed piles.

oxide. The estimated consolidation load in the central London area was about 3500 kN/m 2 in previous geological ages. The depths of the clay beds vary, but, including the under-lying sands, gravels and boulder clay, are typically 50 metres thick over the underlying chalk. London Clay can have a high plasticity index and is often highly shrinkable.

The Ankara-Eskişehir (E-90) highway is the major arterial highway between the western settlement areas and Ankara's city center. A few years ago, due to increasing traffic load and as a precaution to decrease traffic congestion in the coming years, several widening projects have begun along the E-90 highway, adding lane capacity.

Argillaceous describes rocks, sediments, or formations that are composed primarily of clay-sized particles. The term is derived from the Latin word "argilla," which means "clay." Argillaceous materials play a significant role in sedimentary processes, rock formation, and the characterization of various geological environments. Key …

The Tamusu mudstone used in this study taken from the Tamusu area of the Bayin Gobi Basin, Inner Mongolia. This region is a candidate site for China's argillaceous rock geological repository for HLW [[33], [34], [35]].As shown in Fig. 1 (a), the argillaceous rock stratum in the Tamusu pre-selection area under study is the lower part of the upper …

The slake durability test device was primarily designed for argillaceous rocks (clay-bearing) such as shale, claystone mudstone, and marl by Franklin and Chandra (Franklin JA, Chandra R (1972) The slake-durability test. Int J Rock Mech Min Sci 9:325–341). Later, the International Society for Rock Mechanics standardized the test …

The pelitic content of argillaceous rocks, i.e., the fraction with particle size less than 0.01 mm, accounts for 51–83% (average of 69%) of the total rock mass. The sand content of argillaceous rocks accounts for 1.5%, on the average; the silt content ranges from 11 to 50% (average of 21%); and the average content of carbonate cement is 10%.

In this study, we investigated the behavior of a pile constructed on limestone rock under axial loading using a numerical approach. A parametric study was performed based on the full-scale pile load test results and the geotechnical reports on the site. Different values of unconfined compressive strength were implemented to …

argillaceous Applied to rocks that are silt - or clay -sized sediments with grains less than 0.0625 mm in diameter. They account for more than 50 per cent of sedimentary rocks and most have a very high clay mineral content. Many contain a high percentage of organic material and can be regarded as potential source rocks for …

In the case of argillaceous siltstone, friction played a decisive role in load-bearing capacity. The porosity of the argillaceous siltstone reached 19.98 %, and mineral particles smaller than 38 μm accounted for 71 %.

Elastic-plastic axisymmetric finite-element analyses were performed to investigate the side load-transfer mechanism of drilled shafts socketed into cohesive …

Tendency to chemical cement. Ash: unconsolidated fragments under. 4 mm. Tuff: consolidated ash. Volcanic Breccia: angular fragments over 4 mm. Agglomerate: large proportion (>25%) of bombs. These rocks are classified on the proportions of vitric, crystal (mineral), or lithic material they contain, for example, "vitric lithic ash," or "crystal ...

Among others, key reasons for examining the characteristics of these argillaceous rocks include the ability of such rocks to accommodate deformations without extensive damage and rupture and their inherent self-sealing capacity that enables maintenance of low rock mass permeabilities (Horseman, 2001; Maßmann et al., 2009; …

An analogous example to illustrate the importance of texture in argillaceous limestone is shown in Fig. 11. This 165-year-old courthouse in Kingston is made of local limestone similar to the formations discussed in this work. The effects of weathering have highlighted the texture and resulting damage in these vertically loaded columns.

The Cobourg Limestone is a low-permeability argillaceous rock that forms a part of the Paleozoic sedimentary sequence found in southern Ontario, Canada. The limestone has a heterogeneous fabric consisting of nodular regions of calcite and dolomite and argillaceous partings of a similar composition but with a low clay content, which …

Argillaceous limestone (AL) is comprised of carbonate minerals and clay minerals and is widely distributed throughout the Earth's crust. However, owing to its low surface area and poorly active sites, AL has been largely neglected. Herein, manganic manganous oxide (Mn3O4) was used to modify AL by an in-situ deposition strategy through manganese …
