摘要：Naturally soils are formed by weathering of parent rock. These soils are generally subjected to dryingdue to natural environmental fluctuations, human interventions and various engineering activities. During drying, thesoil loses insitu moisture content from the soil matrix and exhibits volumetric reduction, i.e. shrinkage. Due to this, soilloses its integrity and in given situations, may lead to erosion and cracking. Such cracking can adversely affect theapplications and properties of fine-grained soils. Cracking has been reported to be detrimental in case of soilapplications such as moisture barriers, landfill liners, embankment cores, excavations and stability of slopes. This lossof moisture content from soils mainly depends on ambient temperature, humidity, chemicals. However, most of naturalsoils are saturated or unsaturated, subjected to drying. With this in view, efforts have been made to determineevaporation rate from extensive drying laboratory methods such as Temperature controlled oven, desiccator and Airdrying. Using these methods, studies were conducted for various types of soils. From the results it has been observedthat evaporation rate is high at temperature 50⁰C, whereas constant at 40⁰C with air drying and low in desiccatordrying. Also, it has been observed that drying time varies with method and soil.
