Dynamic Properties of Spatially-Varied Pond Ash within a Coal Ash Pond

As all of us know that ash pond deposits consist of large compressiblity,less bearing power,that is why large amount of these weak land sections gets abandoned or squandered.These slumy areas have less tangential shear force. As we know our country population is growing day by day.In future ,it will become very difficult to acquire any piece of land for construction of buildings and any other engineering structures.Nowadays many improvement methods for these low quality soils are implementedwhich makes them fit for use for common practices which can be carried out by these soils.As ,this is great area of concern for many highly standard people and other common organisations .On one side growing population with rapid increase and other side lot of sections of land gets trapped up under these ash deposits.A lot of studies and observations have been evaluated about inducing stone columns at plastic Cohesive soils.But yet no such works or observations have been implemented on these weak deposits.So in current study our main efforts relies upon testing these weak deposits of soil individually and after getting upon results from them,we try to observe these weak soils on treating them with some segments of fresh stones and then observe the variations and differences between first and second stages of these testing programmes.

Increasing Trends

Coal ash is a major component of solid residue resulting by coal-fired thermal power plants. Trace elements like Mn , Cu , Zn , As , Se , Mo and Pb in fly ash and pond ash samples collected from ten coal-fired thermal power plants in India, and crops (rice, wheat, maize grain and straw and onion bulbs) grown on coal ash treated soils at Angul, Bakreswar and Farakka sites of India have been analysed at Institute of Physics by Particle Induced X-ray Emission and Energy Dispersive X-Ray Fluorescence techniques. Our analysis shows that the concentrations of trace elements of grains are higher than in straws. Increasing trends in the uptake of micro-nutrients by the crops due to application of coal ash, were recorded, but within permissible limits.
