Abstract

The cement industries causing environmental hazard and global warming due to emission of carbon dioxide. Approximately 900kg of carbon dioxide is released in the process of manufacturing of cement.  In order to lessen the carbon footprintcaused by theproduction of cement on atmosphere, waste which are generated by industries is used as admixtures in this present study, so that the environmental hazard and natural resources consumption is mitigated. 75million tons of fly ash which are veryallure in silica are used as landfill in India. Egg shell powders which are rich in calcium are thrown away as a waste. In the present study, these two wastes are utilized as a partial replacement of cement and various properties of concrete like workability, compressive strength and split tensile strength were determined. Egg shell powder fixed to 10% and fly ash varied up to 30% (10%, 20% & 30%). From the Experimental investigation it is recommended that the replacement of cement with 10% of egg shell powder and 10% of fly ash is optimum, so that there is increase in compressive strength of concrete with reduction in the use of cement. It is clear that for 100 bags of cement, 20 bags of cement can be saved at 10% partial replacement of egg shell powder and 10% of fly ash with cement”.
