Amount of water in saturated compacted bentonite samples at various temperatures

Popis výsledku v původním jazyce

The aim of this work is to experimentally check amount of water in fully saturated bentonite under various temperature (25 °C, 95 °C a110 °C) and dry densities (1.35 - 1.75 Mg/m3 ). The degree of saturation was chosen for evaluation as first and then apparent density of pore water was used. Two Czech materials were chosen for testing: magnesium-calcium bentonite from Rokle deposit and Naactivated bentonite from the same area. The results are expressed as dependencies of degree of saturation/ apparent density of pore water on both dry density and temperature. The results on both materials showed that the degree of saturation (evaluated according to standard method for soils) at full saturation state increases with dry density and cross the theoretical maximum - value of one. The reason of this behaviour is that some of the pore water in bentonite is strongly bound and its density is higher than for free water. These results are in line with some observation in literature and previous ow
