Abstract

Investigations of the quantity of water of the monomineralic clay-water system at the moisture equal to the plastic limit.A b s t r a c t. The paper presents investigations into the relationship between specific surface area of two monomineralic clays and their plastic limits. Two clays – sodium montmorillonite and calcium kaolinite were used to study. For montmorillonite, the quantity of interlayer water at plastic limit is approximately 30% of water content. The number of the layers of water molecules on the external surface area ne = 13÷14. For kaolinite (i.e. non-swelling clay minerals which only contain water on external surface area), the number of layers of water molecules on the external surface area ne = 63.
