Strength Characterization of Stabilized Class ‘F’ Flyash Using Class ‘C’ Flyash
One of the major sources of power generation in India is thermal power plants. Unlike other countries, the flyash generated in India has poor pozzolanic content (CaO < 10%) and classified as Class ‘F’. The generation of flyash has already reached more than 130 million tons per annum and disposal of flyash is a challenging problem today. Interestingly, the flyash generated from Neyveli Lignite Power Corporation, Tamil Nadu, alone is bearing a classification of Class ‘C’ type flyash which has free reactive silica and high pozzolanic content (CaO > 15%). An attempt is made to improve the engineering properties of flyash Class ‘F’ by adding flyash Class ‘C’ at various percentages. It is found that the γd max, unconfined compressive strength and CBR of Class ‘F’ flyash increased significantly with the addition of increasing percentage of Class ‘C’ flyash. It is concluded that the large-scale utilization of Class ‘F’ flyash can be effectively handled by adding another Class ‘C’ type flyash for various geotechnical engineering applications.
