Abstract

The soil which contains salt is known as SALINE SOIL. These salts occur naturally in soil and water. Salt in soil can also come through some artificial processes like irrigation. Saline soil scattered wide range of Andhra Pradesh. Its presence causes engineering problems, which arising for Structural problems, due to collapse behaviour, when moisturizing with water from any source, due to the rapid melting of the salt molecules surrounding soil granules, leading to the disintegration of the ties of the soil. This study sheds light on the possibility of stabilizing saline soil, mixed with some available additives:(5%, 10%, 15%&20% of Vitrified Polish Waste) and investigates its strength. The soil used in this study was natural saline soil with 10% salinity retrieved from a region near machilipatnam beach. Number of tests was conducted using laboratory models. The best improvement was achieved by adding 10% Vitrified Polish Waste. The CBR value is increased by 37% by adding 10% VPW, when compared with virgin Saline Soil.
