Performance of Recron-3S Fiber with Quarry Dust in Expansive Soil Stabilization

Geotechnical engineering face various problems while designing the foundations on highly compressible clayey soil due to poor bearing capacity and excessive settlement Utilization of industrial waste materials in the improvement of soils is a cost efficient and environmental friendly method. Stabilization of the expansive soil is studied by using Quarry Dust and Recron-3S fibres. This paper includes the evaluation of soil properties like compaction and California Bearing Ratio (CBR) test. Detailed experimental study has been undertaken to investigate the characteristics and behavior of expansive soil mixed with Quarry Dust and Recron-3S fibres with different percentage. From the experimental results, it has been observed that various properties of soil added with these stabilizers at certain percentage show remarkable positive changes as compared to the natural soil. The value of compaction parameters has increased enabling increase California Bearing Ratio which indicates that improved in strength. From these results, it was found that optimum Quarry Dust and Recron-3S fibres 20 % and 1.5 % respectively gives the maximum increment in the CBR compared with all the other combinations.
