Geotechnical Characterization of Dredged Material and Effect of Lime Stabilisation on its Strength Characteristics

Abstract

Increase in developmental activities and the limited availability of suitable sites for civil engineering project construction is greatly encouraging engineers to consider improvement of weak soil deposits for constructing infrastructures. Among various weak soil deposits, “Dredged Material” from famous Lakes is causing serious health and environmental problems. Dredging of lakes generate lot of waste material, which needs to be disposed-off methodically without disturbing environment. Many Researchers have reported that geotechnical properties of dredged material qualify it for use in the manufacture of high value advantageous products. For all applications, a brief study about Geotechnical characterization of dredged material is very important, which will help in proper use of this material as well as sustainable development of the Dal Lake. Therefore, in this study, an attempt is being made to highlight some geotechnical properties of this solid waste for its bulk utilization in various construction activities. The stabilization of the dredged soil with lime is an effective means of chemical stabilization of soils and it is seen that the index and engineering properties of dredged soil are significantly altered by the addition of lime. A significant step is being taken by this study to achieve economic use of construction materials by attempting to prevent the wastage of such soil material through the improvement of its properties to meet the requirements.

The Behavior of Dredged Soil-Shredded Rubber Embankment Stabilized with Natural Minerals as a Road Foundation Layer

“…Over the past few decades, the problems caused by dredged soil from the bottom of the river channel, reservoirs, or swampy areas have caused health and environmental problems [1]. This problem can be a challenge for geotechnical engineers contributing to the construction field.…”

Compressive Strength Characteristics of Trass Stabilized Dredged Soil

“…To maintain the maximum function of the dam, annual dredging activities have been applied at the Bilibili reservoir. From these activities, the geotechnical characteristics of dredged materials have become another important issue for consideration (Mohammad et al, 2018), which needs to be deeply investigated to determine the conditions and prospects for its application. Several laboratory tests on this material indicated that its mechanical properties were insufficient for use in construction fields.…”
