ARTICLE INFO ABSTRACT Article history: Received 13 April 2016 Accepted 21 June 2016 Published 28 June 2016 Keywords: Clay brick, waste, water treatment plant, disposal hazard, alum sludge Background: water treatment plant produced waste during the process of water purification that is fit for drinking, This waste is known as Alum sludge (AS). Alum sludge when is disposed, pose a threat to the environment, though there have been existing method to dispose of this waste but they are said to be unfriendly due to the effect on human health and the environment at large, the waste generated from this treatment process are disposal in the water body which results in constant accumulation of aluminum concentration in the water body that causes skin diseases, Alzheimer and other illness. Utilizing this waste for the production of bricks and other construction materials will eliminate the hazards and future pileup facing alum sludge and other waste. In this research alum sludge (AS) will be used in an optimum proportion leaving alum sludge constant up to 70% incorporated with Clay (CL) and Silica fume (SF) and fired under temperature of 1150°C. Objective: This research focus on utilizing waste from water treatment plant (alum sludge) in replacement of clay in clay brick production and the addition of silica fume as an additive to improve the strength of brick. Results: The result from compressive strength and water absorption shows that the mix proportion of alum sludge, clay and silica fume in percentages of 70:24:6 and 70:20:10 had the best results for compressive strength 28.4MPa and 28.7MPa and water absorption 11.77% and 13.5% which met the requirement of a load-bearing brick as specified in British Standard (BS), though samples of all mix except control passed soundness test and efflorescence. Conclusion: It is concluded that the optimum proportion to produce brick from alum sludge clay and silica fume is 70%, 24%, 6% and 70%, 20%, 10% respectively and that utilization of alum sludge for brick production will eliminate the disposal hazards and make quality bricks available in the market. INTRODUCTION These days the race for a green building material have been at the increasing side, researchers are now taking out time to research more on materials that will be of great benefit to the environment and the same time fill the gaps of the conventional building bricks which have been in existent for a long time now, by using waste materials to replace clay in brick production either partially or fully (Sandeep et al, 2014). Brick have been judiciously utilized for building for a very long time and it can be marked as a historical building material which has never fade till date (Lianyang, 2013). Water treatment plant produces a solid waste which is referred to Alum Sludge from purification process involved in water treatment. Treatment plants on daily bases produce large quantities of Alum sludge as a result
