Abstract. The changes in properties and behaviour of clays when exposed to the influence of various substances are known to a very limited extent, in particular with regard to clays in undisturbed condition. Most of the colloid chemical laws established for diluted colloid solutions are unsuitable for explaining the behaviour of undisturbed clays.اقرأ أكثر
