Clay brick manufacturing is a sector which involves a lot of firing processes requiring higher temperature. To maintain this temperature, large amount of fuel in the form of wood, coal, biomass etc. need to be burnt in the kiln causing serious issues of air pollution. Also, with the increase in the number of industries coming up, large amount of un-disposable waste gets accumulated. If suitable remedies are not adopted for its safe disposal, it may pollute the water bodies through runoff. This project is an effort to reduce the brick firing temperature in the kiln to about 600 °C thereby reducing the cost of production and making the whole process environmental friendly. This work will put forward a suitable alternative for the safe disposal of industrial debris like quarry dust and glass powder by incorporating them as a partial substitute for river sand which is one of the costly constituent of clay brick and thereby further reducing the cost of production. Experimental results showed higher compressive strength of 21.31 N/mm²when the brick was casted with mix proportion of Cement: Sand: Red earth: Glass Powder: Quarry Dust = 4:1:1:1.5:2.5. The strength measured at temperature 600 °C met the requirements of the National Standards.
