Drying Changes Consistency Limits
This study focuses on the effects of drying on consistency limits. To observe the drying effects, samples for Atterberg limits were prepared (i) by starting from in situ moisture content without any drying, (ii) after drying at 60°C, and (iii) after drying at 110°C oven. When the samples were prepared by starting from their natural moisture content, the liquid limit values was 35% to 81% (1% to 26% higher with respect to the case of no drying) and plasticity index was 0% to 31%. Organic content of the samples were determined by loss on ignition test and were in the range of 4.3% to 12.1%. The mineralogy of the samples was investigated via XRD and SEM, and halloysite mineral was encountered. It is concluded that soils containing organic matter, and/or formed by weathering of volcanic rocks should not be oven dried when soil mechanics index tests are to be conducted, since their properties are significantly influenced due to irreversible dehydration.
