Stabilization of Red Soil by Using Walnut Shell Powder, Walnut Shell Ash and Rice Husk Ash

Because of the poor quality connected with it and the reduction in the type of index and engineering qualities of the soil, soil stabilization is now an unavoidable activity. It has been improved with the help of reinforcing the environment. Red soil, often known as red earth, is made mostly of kaolinite clay, as well as slit and fine sand. The presence of significant levels of iron oxide gives it its red hue. It has a lower humus concentration and is less clayey and saltier. This soil is acidic and incapable of retaining moisture. The amount of nitrogen, phosphorus, and lime in the soil is quite low. Using walnut shell powder, walnut shell ash, and rice husk ash, this study evaluates the advancement of workability, compressibility, and compaction characteristics, as well as the physical features of highly plastic clayey soil. The treatment of Red Soil with RHA, Walnut Shell Powder, and Walnut Shell Ash resulted in an overall decrease in MDD and an increase in OMC as the RHA content increased. Because cement is more expensive than RHA, construction costs may be reduced. Stabilizers such as rice husk ash, walnut shell powder, and walnut shell ash are useful and efficient. The use of these stabilizers will improve the strength of Red Soil.
