ABSTRACT

The engineering characteristics of soils such as black cotton in Kenya are known to be complex and problematic in the sense that their behaviour cannot be satisfactorily interpreted on the basis of conventional concepts that characterise soils in temperate regions. In most cases therefore, they have been disregarded and discarded as useless construction materials. In this study, the effects of a liquid chemical stabilizer, Con-Aid, on some of the problematic microstructural related properties and engineering behaviour of black cotton soil are examined and an attempt made to analyse the concomitant characteristics.
