Using a granular-mechanics code, we study the impact of a highly porous granular body on a hard wall. The projectile consists of monodisperse adhesive micrometer-sized silica grains. For the impact velocities studied, ...

We simulate the process of compaction under vertical tapping for a two-dimensional system of particles deposited in a rectangular box. The particles consist in regular pentagons and our main objective is to analyze the ...

Simulations of granular packings in 2-D by throwing disks in a rectangular die are performed. Different size distributions as bimodal, uniform and gaussian are used. Once the array of particles is done, a relaxation process ...

This work presents results of field and laboratory tests using a Dynamic Cone Penetrometer, DCP. The tests were performed in order to evaluate the use of the equipment in sand for the control of bearing capacity of shallow ...

This research studies the influence of the pozzolanic activity of the calcareous and basalt in the resistence behavior of the compressive strength of high performance self-compacting concrete (HPSCC). The selected aditives ...

An alternative of decentralized in-situ treatment for wastewater from condominiums based on aerobic granular biomass is proposed in this research to promote water reuse. It was demonstrated at a laboratory scale that it ...
