Geotechnical Characteristics of Thermal Powertech Fly Ash from Krishnapatnam, Nellore
Thermal power plants continue to produce large quantities of fly ash, which becomes the source of pollution of groundwater, besides consuming large areas of valuable land for disposal. Geotechnical engineering provides vast scope for utilization of fly ash as a substitute to soil in embankments and subgrades. Knowledge of geotechnical characteristics of fly ash helps to promote bulk utilization of fly ash. This paper investigates the physical, morphological, index and engineering characteristics of fly ash (hereafter referred as TPFA) from Thermal Powertech Corporation India Limited, Krishnapatnam, Andhra Pradesh, India. The OMC and MDD of TPFA have been determined under Indian Standard (I.S.) Heavy (modified Proctor) compaction. The shear parameters, CBR and permeability of TPFA, have been determined at OMC. Lime (0–10%) and polyester fibers (0–6%) are used as a stabilizer in different proportions to study possible improvement in engineering characteristics of TPFA, and the results are presented in this paper. The results are analyzed, and suitability of TPFA for use in embankments and subgrade, as a substitute to soil, has been assessed. The results of the study are expected to enhance the awareness among the engineers and help to promote potential use of TPFA in embankments and subgrades, saving soil thus leading to sustainable development.
