Abstract: (19054 Views)
The main purpose of this research is evaluation of effect of chemicals on permeability of
sand- bentonite mixtures. The coefficients of permeability of sand- bentonite mixtures in water,
solutions of sodium and calcium chlorides, sodium hydroxide, acetic acid, methanol and carbon
tetrachloride were calculated using parameters obtained in 1- D consolidation test and Terzaghi’s
theory. At each void ratio permeability of samples in water is the lowest and that for carbon
tetrachloride is the highest. For all fluids the permeability index Ck is decreased as the percentage
of sand is increased. The largest Ck belongs to the samples tested in water and the smallest Ck
belongs to the samples tested in carbon tetrachloride.
