One dimensional static and dynamic compression behaviour of foam glass aggregate

Abstract
Foam Glass Aggregate (FGA) has a wide particle size distribution, in addition to being lightweight and thermally insulating, which extends its potential applications to various infrastructure and construction purposes. For infrastructure projects, it can be used as a lightweight backfill material, allowing the use of soil-improvement methods to be dispensed with in soft subsoils. In buildings, it can be used as thermal insulation under floors, thus helping to improve the energy efficiency of buildings. It acts as a static load for building and earthwork structures, while vehicles or forklift cyclic loads act in case of pavements and industrial floors. It is essential to investigate the effect of different compaction ratios in order to ensure efficient use of materials. In this study, the effects of different compaction ratios (10%, 20%, 30% and 40%) on the elastic modulus (Eoed) and dynamic parameters (Resilient modulus) of the material were investigated. For cyclic loads, elastic and plastic deformations were separated to determine the short and long term behaviour of the material. Different deviator stresses were operated on the FGA for both static and cyclic loads. The results were evaluated by comparing the behaviour of FGA under static and cyclic loads.
