Abstract – Building materials form a very crucial part of any Construction Project. Construction agencies are always on a look out for innovative alternative building materials that are not only cost-effective but also functionally efficient and environment friendly. The latter factor is the need of the hour. Ever increasing demand of the bricks to be used in construction activities cannot be met alone by the traditional clay bricks . The production of these bricks not only depletes the fertile soil underneath but also causes air pollution. The other menace that disrupts the environment is the production of different types of Industrial wastes that is dumped into landfills thereby making it useless. This research is designed to address the best mixture of virgin material clay and waste material (grog-Spent refractory waste ) for burnt as well as un-burnt brick production and to evaluate efficiency of it. Percentages of grog replacement with base material is done from 10% to 60% by taking all intermediate percentages for burnt bricks production. For unburnt bricks the research has investigated the use of lime or Portland cement as an activator to an industrial by-product (Ground Granulated Blast furnace Slag-GGBS) to stabilize the base material ( clay ). Result of burnt bricks shows that replacement of grog upto 35% satisfies all minimum criteria as per IS 3495 (1992) Part 1 to 4 of compressive strength of 3.5 N/mm2 and water absorption of 20% . Result shows that grog added bricks are achieving higher class of bricks than control bricks. This result demonstrates that the grog can be used as partial replacement of clay effectively upto 35% for in burnt clay bricks. Also bricks prism made from grog added bricks are giving better results in compression and flexure than control bricks prisms. Results of un-fired clay bricks shows the highly positive results in terms of sustainable, energy efficient and environmentally friendly building material.
