Abstract Fly ash is gaining importance as a resourceful and commercial material which has market value. The fly ash is the residual waste which is obtained as a by-product after combustion of pulverised coal in thermal power station. The fly ash can be reused, recycled and can be compounded with suitable inorganic chemicals to get value added product. It can be converted into hard and strong tiles and many more value added products hence fly ash has got prime importance in waste management. The present paper deals with the study of electrical properties and electrical resistivity of alkali activated fly ash composite. These fly ash composites have very good compressive strength and can be used as tiles or other building materials. The tiles were prepared by compounding fly ash, lime and sodium hydroxide. Electrical resistivity and other electrical properties are also studied along with temperature and frequency. The correlation also tries for best fitting application. The measurements of electrical resistivity over a wide range of temperatures as per IEEE standards. Empirical relations developed by Bickelhaupt, which are based on the chemical composition of fly ash for calculating the electrical resistivity, which are used to calculate the theoretical value for given experimental conditions.

Electrical resistivity, waste management, compressive strength.
