USCS classification is based in part on particle-size distribution, but also includes consideration of organic matter content and the soil plasticity as defined by the Atterberg limits (liquid limit and plastic limit). USCS considers all particle sizes, including gravel (>4.76 mm), sand (4.76 mm-0.074 mm), and silt and clay (<0.074 mm). 3.

The drying behavior of solids can be characterized by measuring the moisture content loss as a function of time. Convection is possibly the most common mode of drying particulate or sheet-form or pasty solids. Drying commonly describes the process of thermally removing volatile substances to yield a solid product. Energy transfer as heat from ...

Particle classification is essential for geotechnical engineering practice since particle shapes correlate with the mechanical and hydraulic properties of sand layers. Traditional shape classification is tedious, subjective, and time-consuming because it depends on manual visual comparison with reference particles. This study demonstrates …

Every piece of sandpaper carries a specific grit rating. This rating describes the size of abrasive materials which is affixed to the paper's backing. As a general rule, the higher a sandpaper's grit number, the finer its abrasive media. On the other hand, lower grit sandpaper features much larger abrasive media.

Abstract. While the identification of sand type helps naturally approximate physical and mechanical properties, it is challenging to judge sand types without prior information. This study attempts to identify the sand type in 2D grayscale images by using convolutional neural networks (CNNs). Six different sand samples with high geometric ...

The dune classification (or detection) problem (DCP) we deal with consists of identifying the presence or absence of sand dunes from remotely sensed images of the surface of Mars. In order to solve this problem, support vector machines [10] and random forests (RF) [13] were used with good results in [14]. Here, we propose a different …

The availability of sand and gravel (for concrete) near the dam site would reduce the cost of a concrete dam. Spillway is a major part of any dam and its size and type and the natural restrictions in its location will affect the selection of the type of dam. Spillway requirements are decided by the runoff and stream-flow characteristics.
DetailsThe sand type classification performed in the previous section utilized grayscale images that contain information on the surface texture (degree of contrast-homogeneity within a particle) and contrast within sand particles as well as particle shape (i.e., boundary morphology between sand particles and black-colored background). ...

The results demonstrate that sand classification using a larger number of sand types resulted in a lower classification accuracy. Classification accuracy of individual particles achieved using CNN were 10%-15% better than those achieved using NN. CNN can automatically and adaptively learn the spatial hierarchy of features which is superior to ...
