STABILIZATION OF CLAYEY SOIL USING CHEMICALS Bhawna Sahay1, Prof. V.K.Arora2

ABSTRACT: Soil stabilization is a technique of enhancing the geotechnical properties and strength of soil to modify the bearing capacity and durability of weak soil. There are numerous methods of stabilising the soil such as soil replacement , grouting ,reinforcing ,chemical, mechanical, electrical method, using additives such as fly ash, rice husk, gypsum and cement. Chemical stabilization with lime and sodium hydroxide is time saving method. All these chemicals are highly reactive in nature and react with clay particles during stabilization process which leads to improve the geotechnical properties of soil.

EXPERIMENTAL WORK
1. LIQUID LIMIT
2. PLASTIC LIMIT
3. SPECIFIC GRAVITY
4. COMPACTION
5. UNCONFINED COMPRESSIVE STRENGTH
All these are laboratory test which conduct on soil sample individually or with combination of soil with chemicals, the percentage of used during testing is 3%, 7%, 10% of lime and 8%, 12% 16%, of sodium hydroxide. Chemical stabilizer is used for mixing of chemicals with soil in fine proportions so that during testing chemicals should be thoroughly mixed with soil as these chemicals are available in powder form or in chips form which are not easily mixed.

from it are easily released in the available forms to be taken up by the plants from the soil system. The fast release characteristic of nutrients from inorganic fertilizers also opens the avenues for considerable losses. In greater amounts, these nutrients are being leached down with water, volatized in the air if it is nitrogenous, fixed by clay, fixed by macro as well as micro-organisms and go with eroded soil during run-off. Now, it is generally accepted that the inorganic fertilizers have low efficiencies…
