Effects of particle shape and size distribution on the ...
2013-10-23 The effects of particle shape and size distribution on the constitutive behavior of composite soils with a wide range of particle size were investigated. Two comparable sets of specimens were prepared: (1) mixtures of fines (clay and silt) and an ideal coarse fraction (glass sand and beads), and (2) mixtures of fines and natural coarse fraction (river sand and crushed granite gravels).

EFFECT OF PARTICLE SIZE ON THE MECHANICAL
2016-9-9 The composite made up of 1760μm particle size at 50% volume content yielded the maximum impact strength of 23.2Jm-2. It is concluded that decrease in particle sizes increases the tensile strength and flexural strength, but causes a scattered diagram in hardness strength. In impact test, the strength increases with increase in particle size.

Effect of content and particle size distribution of
2010-4-1 In addition to the content of CA, both the maximum size of aggregate and their grain size distribution have a substantial effect on the compressive strength of the NSC and the HSC. It is believed that in order to improve the mechanical performance of concrete material, the granular fraction incorporated into the concrete mixture should be optimized as well as the volume of the cement paste.

Effect of Thermal Treatment on Brazilian Tensile
2018-1-23 Grain size distribution can affect the granite tensile strength, i.e., the average tensile strength decreased with increasing average grain size, and the heterogeneity of grain size also lowers the tensile strength. The tensile strengths of FG1 and FG2 were 12.39 and 8.54 MPa, respectively. The MG had the lowest tensile strength of 7.27 MPa.

Classification of Aggregates: Grain Size, Density,
2018-3-29 Classification of aggregates based on: Grain Size. The size of fine aggregates is defined as 4.75mm or smaller. That is, aggregates which can be passed through a number 4 sieve, with a mesh size of 4.75mm. Fine aggregates include things such as sand, silt and clay. Crushed stone and crushed gravel might also fall under this category.

Relating Hydraulic Conductivity to Particle Size Using
In terms of hydraulic conductivity, particle shape will affect the tortuosity and therefore also the hydraulic conductivity, but the focus here is solely on the governing effect of the pore size. The cylindrical sample initially contained approximately 6,000 spheres of d = 2 mm and contained around 155,000 spheres at the end of compression.
