ABSTRACT
Arsenic contaminated sludge can be found from the treatment of arsenic contaminated ground water. Lake of management and reuse of this sludge can create further environmental problem as there is probability of mixing with soil and water. In this paper, an effort is taken for the use of such waste. Here, effectiveness of using this sludge in making ornamental brick has been analyzed and justified. The detailed study was made upon the suitability of sludge in making bricks. Results of different tests indicate that sludge proportion is the key factor for determining the quality of ornamental bricks/tiles. The compressive strength of ornamental bricks decreases with increase of sludge proportion. This study showed that arsenic contaminated sludge could be used safely up to 4% for making ornamental bricks. Because after that limit the quality of bricks or tiles fall markedly
