Molecular dynamics data for modelling the microstructural behaviour of compacted sodium bentonites
نویسندگان
چکیده
The water retention curve deduced with low content data allows the modelling of bentonite void ratio associated pores located inside clay aggregates, or micropores. However, if both and microporosity continue to increase, latter can no longer be directly obtained from former, because, in that case, presence existing between aggregates (macropores) may not negligible. Therefore, it is easy obtain experimental evidence contrast whether model's extrapolation microstructural under dry conditions valid for higher contents. This work analyses use molecular dynamics models assess validity such extrapolations, defines variables needed compare results laboratory experiments. encouraging agreement contributed confidence proposed procedure, which enabled a new strategy uses model macroscopic behaviour compacted sodium bentonites.

the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...
