Dear Colleagues,
In investigation on effects of wetting and drying cycles of expansible
clays, I encountered with two opposite theories. Some of investigators
have reported that such clays cause increase in swelling pressure and
swelling percentage. But others have reported decrease in these two
parameters. In one of literatures, the editor has related these different
results to the degree and amount of drying of clays in cycles, but I
believe that there must be other reasons for this.
Do you think there are other causes for these different results?
Please Tell me your idea.
Beast regards
H.Ahmadi
