Soil Stabilization using Fly Ash and Cotton Fiber

Abstract

Mixing of fiber for ground improvement has been practiced for recent years. Many researches has the expected results. This paper mainly deals with the ground improvement technique using both Fly Ash and cotton fiber. The combination of them gives a satisfactory value of its practical application. Both Fly Ash and Cotton fiber are treated as waste materials in our country in spite of having its engineering significances. Here all the tests were performed accepting the Fly Ash percent is 10 for maximum bearing capacity of soil. Three types of sample were prepared as per 0.3%, 0.5%, 0.7% of cotton instances, it deliberately increases the Dry Density of soil up to 48.05 KN/m3 where as normal unreinforced soil sample gives about 22 KN/m3. The Ultimate bearing capacity increases up to 80.65 Kpa whereas the unreinforced soil sample gives for result of California Bearing Ratio (CBR) test gives desired value (23%) than unreinforced soil (17%). The CBR test is performed only for 0.7% of cotton fiber where maximum stress is found. The most significant part in this study is to show the on cotton fiber for ground improvement technique at different ratio. This paper shows the gradual increase in Deviator stress for UCS tests for the increase in the percent of cotton fiber mixing with Fly Ash. This research may meet the need of ground having low strength at important sites.

Calcium Carbide and Wood Ash as Environmentally Friendly Soil Stabilizers for Enhanced Subgrade Performance

“…This approach demonstrates cost-effectiveness, environmental friendliness, and efficiency, especially when making use of resources that are readily accessible in the local area. Chemical stabilization refers to the process of combining chemicals with particular moisture content to improve the characteristics of soil in various engineering projects [19].…”

“…Krishana & Pavan [19] and Oluwatuyi et al [12] and other recent research have investigated the use of lime-fly ash combinations, epoxy resin, calcium chloride dehydrate, and waste calcium carbide with wood ash as materials for waste management. Together, they highlight the capacity of various materials to modify soil characteristics, with a focus on their advantages, disadvantages, and economic consequences.…”

Stabilization of clayey soil using Gypsum

“…Ultimately, the foundation of any structure should transfer its load to the soil. If a structure is built on weak soil, in course of time, the soil compacts and consolidates resulting in the settlement of the structure (Brahmachary, 2017). The engineering properties of the soil also differ from place to place and depends mainly on soil mineral deposits, water table, soil water relationship etc., because of which soil properties are problematic and unsuitable for construction.…”
