Strength Characteristic of Chenab Soil Stabilization with Bagasse Ash and Cementfor Road Work

摘要

In this paper an attempt has been made to improve the strength properties of Chenab river soil from Akhnoor area (Jammu&Kashmir, India) to be used as sub-gradeby using bagasse ash admixtures with cement. The CBR value of virgin Chenab soilis found to be 3.15 %. Other samples were remoulded by addition of additives in varying percentages of 7.5%, 15.0% and 22.5 % of bagasse ash with either 3 % or 6 % of cement content by dry weight of the soil at Optimum Moisture Content (OMC) and Maximum Dry Density (MDD). Different soil combinations were made by varying percentages of bagasse ash and cement to evaluate the California Bearing ratio (CBR) with different period of curing i.e. on the same day (immediately after bagasse ash and cement mix with soil) and after 7 or 28 days of curing. It is observed that addition of varying percentages of 7.5%, 15.0% and 22.5 % of bagasse ash along with either 3 % or 6 % of cement content by dry weight showed a remarkable improvement in the California bearing ratio.....
