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 ...

Composites are relevant to high-performance materials in the aerospace sector and have attracted attention of scientific technological communities. Bentonites present very fine granulometry which enables their use composites. This study showed development water absorbent composite based on sodium polyacrylate, bentonite coated by epoxy resin. Since there gaps quantification near-infrared spectr...

Bentonite, a common smectite-rich buffer material, is in direct contact with corroding steel many high-level radioactive waste repository designs. The interaction of iron the clay may affect its swelling and sealing properties by processes such as alteration, redox reactions cementation. chemical interactions were investigated analysing Fe/clay interfaces eight bentonite blocks which had been e...

in this study, the vibration behavior of functional graded (fg) circular and annular nanoplate embedded in a visco-pasternak foundation and coupled with temperature change is studied. the effect of in-plane pre-load and temperature change are investigated on the vibration frequencies of fg circular and annular nanoplate. to obtain the vibration frequencies of the fg circular and annular nanopla...

Pinot noir is a grape variety with thin skin, which means the extraction of colour and polyphenols more challenging than other red varieties. The aim this study was to investigate impact protein removal by adding bentonite prior fermentation on wine composition. Four treatments were conducted, including control without addition wines produced three different types bentonites before cold soaking...
