STABILISATION OF YELLOW SOIL BY ADDING SAWDUST ASH AND LIME by Amreen Farooq
Abstract
Abstract
As we know that the soil is a peculiar material. Some waste materials like pond ash, rice husk ash can
be used to make a soil stable. Addition of such materials has a great impact on both physical as well as chemical properties of the soil. By adding such admixtures some of the properties like CBR value, liquidity index , plasticity index , standard proctor test can be improved by adding this. As we know large amount of sawdust ash and lime has been produced all over world. The main aim of this paper was to study about stabilization of clayey soil by using lime and sawdust ash. In this study the soil which was used taken from the local area of Rajouri J&K. The soil was clayey in nature. Moreover, sawdust ash and lime was used as a admixture in this. Firstly the lime was added in soil at a proportion of 5% , 10%, 15% and after that a combination of lime and sawdust was added in it to check the variations in different tests like UCS , Standard Proctor Test and CBR test. After that curing of samples was done. For UCS curing was done for 3 days but for CBR curing was done for 7 days. As we know that the disposal of sawdust ash in an open areas causes many environmental problems so it should not be dumped openly as it is not eco-friendly. The proper utilization of ash in geotechnical applications gives a good solution. From the experimental study it was concluded that sawdust ash act as a good stabilizing agent for both base and sub base course. Moreover, its improvement can also be improved by combining it with other materials to provide a better result for future.
