2018129 · already crushed angular sand throughout shear loading. The shearing behavior of a crushed sand and the resulting particle crushing in the shear zone of a crushed Firuzkuh sand are investigated through a series of ring shear tests. Particle breakage is investigated by comparing the PSD curve with respect to the maxi-mum particle size.

The crushed sand (CS), spread granulometry, is a by-product of crushing rock mass. The desert sand (DS) is an extra fine sand, characterized by a tight distribution of grain size. Containing significant levels of fine sand, these two sands can be both interesting components of the SCC. This research is to incorporate the CS in the composition ...

2021111 · Abstract. The article deals with internal erosion in 0–5 mm crushed sand, a material used in urban facilities. Several methods, designed for natural materials, predicted a risk of internal erosion for the crushed sand. The real risk was evaluated in clear-wall, watertight and airtight, rigid-wall permeameters with lateral piezometers. Each test started …
