(B) Ph.D. Thesis:
Topic: Characterization, Water-interaction and Zeolitization of Class F Lagoon ash
In India, the current production of ash from coal-based power plant is about 80 million tons per year and is expected to increase to 100 million tons by 2000AD. In comparison to other modes of electricity production, the coal-fired thermal power plants generate maximum range of waste types and usually in large quantity. As a result, the disposal and utilisation of waste would need major and continuous focus.
The quantity and the quality of ash produced mainly depends upon quality of the coal used, its pulverization process, the combustion technique adopted, type of collection system employed etc. Also, due to the extensive variability of the coal properties and operation of the boiler, the ash produced varies a lot in its characteristics. Properties of ash vary invariably from one thermal power plant to another. Even at the same power plant the ash properties may vary. These days with an increased attention on proper utilization of the ash, from these power plants, it has become mandatory to characterize the ash before it can be utilized properly.
Self-hardening property is the most important property for ashes. Several researchers have shown that the binding property (self-hardening property) of the fly ash increases with addition of lime, cement and other chemicals. But characteristics of the fly ash as such, as a construction material, has not been studied in details which may be of a great importance in making a judicious choice for fly ash utilization and evolving a methodology to work out the finer details for the same.
Another important aspect is ash-water interaction during wet or slurry disposal. During slurry disposal (commonly adopted method) of fly ash, it reacts with water, which is responsible for transformation of fly ash properties due to the formation of zeolites. Several efforts have been made to synthesize fly ash zeolites and to estimate their effect on fly ash properties. Although, these zeolites are being used in several applications viz. as absorbents for removal of heavy metal ions and other wastes, Some researchers have studied the heavy metal retention on clay, activated granular carbon, fertilizer waste, fly ash and natural zeolite. However, it can be noticed that not much attention has been paid by the researchers on the use of either lagoon ash or synthesis of zeolites from the lagoon ash (or zeolitized lagoon ash) for such applications.
The effect of zeolitization on the physical, chemical, mineralogical, thermal and geotechnical characteristics of the fly ashes is being under emphasized. It is observed that the transformation of zeolites affects the long and short-term behavior of the fly ashes in terms of their compaction, consolidation and shear strength characteristics. Hence for the bulk utilization of fly ash, in particular the rehabilitation of fly ash lagoons, reclamation and filling of low-lying areas, where the fly ash characteristics changes over a period of time are of great importance.
Keeping above points in view, in this research an effort has been made to study the physical, chemical, mineralogical, thermal and geotechnical characteristics of a typical class F lagoon ash. Response of the lagoon ash to alkali activation, and hence zeolite formation, under controlled thermo-chemical treatment, has also been critically studied. The effects on its geotechnical characteristics of the lagoon ash have been studied. Studies have also been conducted to explore the possibility of its application for heavy metal retention from industrial sludge.
(C) Master's thesis:
Topic: A study of one dimensional consolidation test
The prediction of consolidation settlement is normally done from results of conventional consolidation tests using consolidation rings having diameter to height ratio of about three. Previous studies on the one-dimensional consolidation test reveal that the effect of side friction between the sample and the wall of the ring is equivalent to reduction of the applied load. Therefore, the neglect of it would result in lower predicted changes in void ratio and hence in lower predicted settlements. The side friction therefore must either eliminated or its magnitude is assessed so that corrections can be applied. For this purpose, tests have been conducted in a special consolidometer ring with 12-cm diameter. Two type of soil, one Kaolinite and another Bentonite, have been tested. The same soil has been tested in conventional consolidometer ring. The ratios of the values of the parameters as determined from the tow tests have been presented as correction factors for side friction. The effect of application of silica gel in the conventional ring has also been studied.
(D) Experience in Geotechnical Centrifuge:
Used small geotechnical centrifuge (1.5m diameter) for Fly ash Leaching studies. Fly ash disposal presents a formidable problem of colossal magnitude in India since the annual production of Fly ash in India is around 2 million tones and utilization hardly 5%.
Centrifuge Modeling has come up as a viable alternative for geotechnical purposes because of the numerous advantages, like scaling down of model size and time contraction under accelerated conditions. At 200g, 2m of prototype can be modeled by preparing 1cm sample and response of one year can be estimated in 24 hrs.
Leaching studies can contribute greatly to an overall Waste Management strategy by providing an insight into long-term behaviour of the leachable waste by simulating contaminant release in the landfill environment. In my study I have adopted a method of complete characterization of fly ash and simulation of its leaching behaviour based on column tests and sequential batch tests. The leachate is analysed by ICP technique to assess the possibility of migration of toxic elements. At a later stage I intend to simulate ash pond leaching in the centrifuge and to study attenuation of the leachate by natural soil or clay liners.
(E) Graduate (B.E.) Thesis:
My previous adventure was in the form of my B. E. project under which I have done three projects: Industrial Shade Design, Overhead concrete tank Design and, Multistoried Building Frame Design using BASIC programming.
(F) Practical Training:
Apart from this academic research experience I have a short one month work experience with Hooghly River Bridge Commission (HRBC), 2nd Hoogly Bridge, Calcutta, is one of the leading companies specializing in the field of Geotechnical engineering and Construction Management. Working at their office gave me an insight into their various innovative techniques such as Pipe Jacking, Vibroflotation, Sandwicks, different testing of concrete and steels and Diaphragm Walls. On their construction sites I got an exposure to the diverse technical aspects of the construction of Cable Stayed Bridge.
