A Study on Strength Properties of Expansive Soil Treated with Quarry Dust
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 7
Abstract
Expansive soils have problems to civil engineers in general and to geotechnical engineers in particular because of alternate swell and shrinkage, distress is caused to the foundations of structures laid on such soils. Stabilization of the expansive soil is studied by using quarry dust. This paper includes the evaluation of soil properties like compaction, unconfined compressive strength test 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 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 expansive soil. The value of compaction parameters has increased enabling increase California Bearing Ratio in both soaked and unsoaked conditions which indicates that improved in strength. From these results, it was found that optimum quarry dust (10%) gives the maximum increment in the CBR value compared with all the other combinations.
