ABSTRACT
Fine-grained soils containing clay minerals have very high (specific) surface area and good sorption properties, which are important for environmental applications such as rehabilitation of contaminated areas or construction of geological and technical barriers of the repository for the inert and hazardous waste. The specific surface area, which is rarely used in geotechnics, helps to describe the soil and this characteristic is in good correlation with some geotechnical characteristics. In the article, the relationship between specific surface area and some geotechnical properties is analysed, in particular for use in determining the characteristics of the coefficient of permeability.

Keywords: specific surface area, coefficient of permeability, fine-grained soils, geotechnical properties
