In this work, we developed brick by using the granulated blast furnace (BF) slag produced from the Rourkela Steel Plant with lime and sand. Two types of bricks are developed; one is the mixture of granulated BF-slag and lime whereas the other one is a mixture of granulated BF slag, sand and lime. The volume and weight were measured and the bricks were characterized by compressive strength, water absorption capacity and efflorescence testing. From the experiments and analyzed data, it was found that for M-4 sample of lime-slag brick having composition of 20% lime and 80% slag, the compressive strength is the maximum and water absorption (%) is minimum, whereas in the case of lime-sand-slag brick the compressive strength is the maximum at M-6 sample having composition 30% lime, 30% slag and 40% sand whereas water absorption is minimum at M-4 sample having composition 20% lime, 20% slag and 60% sand. The efflorescence test shows that no soluble salts were dispersed over the tested brick indicating a high quality of brick relative to conventional bricks. Hence, from the analyzed data, we conclude that the brick developed with 20% lime and 80% slag is better in quality than the conventionally manufactured bricks.
