The ability of helium gas displacement pycnometry to characterise the reduction adsorbed water density with increasing bentonite content was tested. For this purpose, after obtaining grain (which assumed be constant), an intensive campaign 45 experiments carried out two bentonites for a total 90 determinations, very consistent results. Furthermore, retention curve one fully characterised by 95 ...

Recent research on the behavior of gravelly sands advocate for use skeleton void ratio to characterize their density state. The corresponds grains constituting stress-bearing skeleton. However, such a relies parameters difficult determine in practice, as fraction fine that take part actively load bearing Also, it fails consider effect grain-size distribution (GSD) gravel and sand grains. Theref...
