Abstract |
Fly ash is an industrial waste that can have lot of advantages due to their coherent qualities. For their bulk utilization in constructional activities as a sub-grade, embankments, and fill materials and their geo-technical characterizations has been attempted. In this study three fly ashes have been collected from NTPC, RINL, SEIL and subjected for gradation, consistency, compaction, shear parameters, CBR, etc. They are also exposed for shear resistance at various moisture contents. From the test results it is identified that the three fly ashes are non-plastic, uncompressible and have low specific gravities (7.8-2.1). They occupy less dry densities (1.11g/cc – 1.28 g/cc) with wide variation in their OMC (22-36%). They can also possess high shear resistance values with wide variation of moisture contents. Due to low density, high shear resistance they can be used as fill, embankment and sub-grade material. |
