Abstract—In a developing country like India, population growth demands expansion of metropolitan cities and urban areas. Thus, increasing infrastructural growth has forced the construction industry to look for cheap and suitable materials for construction. In any given area, it is difficult to obtain a pure and perfectly suitable material for construction purposes. It therefore becomes necessary to utilize the available materials either individually or as a mixture to enhance the geotechnical properties. The present study makes an attempt to find a viable solution to save soil and facilitate en masse use of fly ash in conformation with Fly Ash Mission (1994). Physical and chemical properties of Dadri fly ash were investigated in the laboratory. JEOL JSM-6510 Scanning Electron Microscope (SEM), and Energy Dispersive X-Ray Spectroscopy (EDS) were used for the study. The results show that fly ash particles are mostly spherical. Fly ash was classified as class F and almost cohesion-less material. Maximum dry density, optimum moisture content and shear strength parameters of fly ash exhibit that it can be used as an alternative to soil.
