Abstract
Geotechnical engineers all over the world face enormous problems, when the soils founding those structures are expansive in nature. Depending upon the use of expansive soils as foundation support or construction materials, their properties need careful studies to estimate their potential for damages based on volume change with reference to the imposed structural loads and the tolerance of structures for maximum settlement, differential settlement etc. Among several techniques adopted to overcome these problems posed by expansive soils, lime stabilization gained prominence during the past few decades due to its abundance and adaptability (Snethan et al, 1979). Various remedial measures had been practiced over years with varying degrees of success. The main objective of this thesis is to Improvement of a soil property of the existing expansive clay soil without using any admixture i.e. by using of CNS (Cohesive Non Swelling) Soils. An attempt has been made to use these materials for improving the swell, plasticity, compaction, strength and penetration characteristics of problematic expansive soil which will also prove environment friendly. Thus, from this experimental study, a two-fold solution was evolved, i.e., improving a problematic soil and also environmental balancing of existing soils.
