Numerical and experimental study of aggregate blocking in extrusion of mortar is presented.
The studied system consists of a pipe with a nozzle at the tip. Fresh mortar is modeled by …

The interface between soil and structure can be referred to as a soil-structure system, and its
behavior plays an important role in many geotechnical engineering practices. In this study …

This paper presents a discrete element method (DEM) study of confined shear flow to
explore its nonlinear behavior. As a supplement to the analog experiments, the DEM …

This paper aims at studying the shear behavior of mixtures of fine and coarse particles by
classical triaxial tests. The work is performed both on experimental tests and computer …

Concrete walls are constructed by pouring fresh concrete in-between formworks. The
lifespan of these formworks is limited due to the abrasive nature of concrete. The present …

This article presents the interface shearing behaviour of a granular soil layer in contact with
a bounding structure under motion. For this purpose, an elasto-plastic Cosserat continuum …

As one of the constitutive features of the interface, the surface geometry has a significant
influence on the shear behavior. To investigate the influence of surface roughness on a …

Wall roughness plays a crucial role in granular medium-rough wall interface friction. In this
study, an experimental device has been designed to study the influence of boundary …

This paper proposes an algorithm based on particle number probability distribution (PNPD),
which is validated by two classic grading curves of Rosin–Rammler curve and Fuller curve …

Les granulats de béton recyclé (GBR) ne sont pas suffisamment utilisés dans le secteur de
la construction, principalement en raison de leur grande capacité d'absorption d'eau. Ces …
