Effects of Particle Size and Fines Content on Thermal Conductivity of Quartz Sands

Transportation Research Record: Journal of the Transportation Research Board, 2015
The thermal properties of soil have drawn great research attention in recent years. Thermal conductivity is the most important such property, particularly for the design of shallow geothermal systems such as energy piles and borehole thermal energy storage.

Effects of abraded fine particle content on strength of quick-hardening concrete

Cement and Concrete Composites, 2019
Abstract The strength of quick-converting railway tracks is expected to be lower due to abraded fine particles attached to the surface of ballast aggregates caused by gravel friction under repetitive train loading. The effects of abraded fine particle content on the failure process of quick-hardening concrete were investigated using digital image ...

Chemical characterization of atmospheric fine particles in Sapporo with determination of water content

Atmospheric Environment, 1998
Abstract Chemical components of atmospheric fine particles (aerosols less than 2 μm in diameter) were measured every half month in Sapporo from November 1991 to October 1992. Water content of the particles was, in particular, analyzed with Karl Fischer method as well as elemental carbon, organics, sulfate, nitrate, chloride, ammonium, sea-salt ...

Exploring the effects of particle shape and content of fines on the shear behavior of sand-fines mixtures via the DEM

Computers and Geotechnics, 2019
Abstract This report explores the effects of particle shape and content of fines on the shear behavior of sand-fines mixtures using a two-dimensional discrete element method. The contributions of different contact types to the residual shear strength are quantified.

Optimal Values of Fines Particle Content on the Mechanical Properties of Granular Material

2018
With the rapid development of the economy in the southwest China, more and more large projects are built in such areas. However, how to fill and cut well has been frequent problem because the western region is mostly mountainous areas. Especially for filling, in order to protect the stability of constructions, mechanical properties of granular ...

Increasing The Fine Particle Content In Metal Powders For LPBF Through Nanoparticle Dry-coating

World PM2022 Proceedings, 2022
In powder-bed-based additive manufacturing (AM) processes, such as laser powder bed fusion (LPBF) typically the fine particles (less than 20 µm) are removed from metal powders in order to decrease powder cohesion that often results in inhomogeneous powder spreading.

Influence of fine particle content on soil stabilization using KR desulfuration slag

Environmental Geotechnics
This study investigates the potential of Kambara Reactor (KR) desulfurisation slag, a by-product of the steel industry, as a soil stabiliser. KR slag, with low swelling potential, is mixed with three different soils (Sa100, Sb100, and Sc100) at an 80:20 soil-to-KR ratio. The influence of fine particle content on stabilisation effectiveness is evaluated

Fine particle contents in sediment drive silica transport and deposition to the estuary in the turbid river basin

Water Research
Changes in riverine sediment transport are an important part of land-sea geochemical cycling and further impact geochemical element fluxes in turbid rivers. However, as a vital nutrient element supporting primary productivity, silica mobilization from drainage in turbid rivers is overlooked.
