Stabilization of Peat Soil Using Portland Cement, Rice Husk and Egg Shell

Abstract

Peat is a type of soil that is formed from the accumulation of partially decomposed plant material in waterlogged and acidic conditions. It is characterized by its high organic content, dark brown to black color, and spongy texture. Peat soil is typically found in wetland areas such as bogs and marshes and swamps. It has unique properties, including high water-holding capacity and low nutrient availability, which make it suitable for certain plant species but challenging for agriculture. Peat soil is also an important carbon sink, storing significant amounts of carbon dioxide from the atmosphere. It is prevalent in regions with high rainfall and waterlogged conditions, including northern Europe, parts of North America, and some areas in Southeast Asia. These regions provide the necessary conditions for the accumulation and preservation of organic matter, leading to the formation of peat soil. In India, peat soil is primarily found in the northeastern states, particularly in the region of Assam. The wetland areas of Assam, including the Brahmaputra Valley, are known to have peat deposits. Additionally, some parts of the Western Ghats, such as the high altitude regions of Kerala and Tamil Nadu, may also have small pockets of peat soil. In civil engineering, there are several challenges and problems associated with peat soil, Bearing Capacity, Stability, Settlement, Drainage, and Organic Content. Therefore, we are proposing Egg shell, Rice Husk & Portland cement as a choice for soil stabilization of peat soil. This study could contribute to the development of cost-effective and environmentally friendly techniques for stabilizing peat soil, which could have practical applications in geotechnical engineering, road construction, and other infrastructure projects. To calculate the cost benefits and environmentally friendly techniques for stabilizing peat soil, which could have practical applications in geotechnical engineering, road construction, and other infrastructure projects? To find ways of stabilization and improving peat soil to solve the problems pertaining marginal land. To reuse the waste materials for green construction. To increase the bearing capacity of the soil. To compare stabilization with alluvial soil. To gain the knowledge on the behavior of peat soil for the purpose of geotechnical engineering applications.
