| dc.description.abstract | The addition of hydrated lime to clay soils is one of the most common methods of soil stabilization. However, when sulfates are present in the soil, the calcium in the lime reacts with the sulfates to form ettringite, an expandable mineral. This expansion causes a considerable amount of economical as well as structural problems. In this research, a field test method is developed to locate sulfate bearing soils. A permittivity probe is used to measure the electrical conductivity of the insitu soil. The electrical conductivity is then related to sulfate content in soils. Expansion tests were performed to determine the amount of expansion that occurs when lime is added to soils with different sulfate contents. A model that relates the amount of expansion of clay soils to electrical conductivity, is proposed. The use of low calcium lime stabilizers are investigated and proposed as alternative form of stabilizer for sulfate bearing soils. | en |
