La microstruttura di una "locked sand"

Calogero Valore Maurizio Ziccarelli Antonio Casella

subject

locked sand packing density Settore ICAR/07 - Geotecnica grain-contact

description

Nella nota si riportano alcuni risultati sperimentali sul comportamento meccanico di una locked sand. Si descrive la microstruttura della sabbia sulla base di osservazioni al microscopio ottico e al SEM. Si descrivono in particolare i tipi di contatti intergranulari, che sono prevalentemente interpenetranti (concavo-convessi e suturati), gli indici grain contact e packing density caratterizzanti la struttura del materiale, e la loro influenza sul comportamento meccanico della sabbia. I risultati ottenuti sono confrontati con quelli di altre locked sands.
