A Study of Physical Properties of Fine-Grained Soils Under Different Environmental Conditions

Abstract

A Study Of Physical Properties Of Fine-Grained Soils Under Different Environmental Conditions civil project report Naturally soils are formed by weathering of parent rock. These soils are generally subjected to drying due to natural environmental fluctuations, human interventions and various engineering activities.

During drying, the soil loses insitu moisture content from the soil matrix and exhibits volumetric reduction, i.e. shrinkage. Due to this, soil loses its integrity and in given situations, may lead to erosion and cracking. Such cracking can adversely affect the applications and properties of fine-grained soils. Cracking has been reported to be detrimental in case of soil applications such as moisture barriers, landfill liners, embankment cores, excavations and stability of slopes.

Conclusion

The present study was taken up, to study the effect of temperature and chemicals on different types of soils varying from granular to fine grained soils. Based on extensive investigations it has been observed that the drying time varies from method and type of soil. It also been observed that evaporation rate is high at temperature 50⁰C, whereas constant at temperature 40⁰C with air drying, low at temperature 30⁰C, and very low in desiccator drying.
