Abstract: | The disposal of Fly-Ash from power plants and Marble Slurry Dust (MSD) from marble mines and cutting industries have been a major environmental concern over a period of last few decades. This project aims at investigating the geotechnical behaviour of fly ash when mixed with marble slurry dust, so that it can be well utilized for geotechnical purposes. The use of reinforced pond ash in road construction will lead to eco friendly and profitable utilization of pond ash, with improve properties, which otherwise is a waste product. A sample of pond ash was obtained from Rajghat Power Station, Delhi and sample of marble slurry dust was collected from Naraina Industrial Area. A number of experiments were carried out to find out particle size distribution, specific gravity, compaction behaviour, X-Ray Diffraction, Scanning Electron Microscope, swelling Index, and suitability to use in road construction. MSD content was varied by 10%, 20%, 30%, and 40%. Pozzoloniac reactions between lime and pond ash gives a strong cementitious product. Presence of various minerals and their interlocking were studied. The UCS of the samples was giving increasing trend with increase in the MSD percentage as well as with curing time. Direct shear test shows increase in cohesion and friction angle with increase in MSD% and curing time. The overall CBR value of the mix was extraordinarily increased at an optimum percentage of MSD, though it has showed increasing trend in every mix proportions with increase in curing time. |
