Utilization Of Dyeing Industry Sludge In Developing Green And Sustainable Brick And Paver Blocks

Abstract

Tiruppur city is very popular for export of knitting garments. The dyeing industries generate enormous quantity of effluent during their process. As a measure of reducing adverse effect of these effluents on environment, industries are enforced to adopt zero liquid discharge practice. This ZLD process results in the generation of large amount of sludge.  In this study an attempt is proposed to utilize dyeing industry sludge in paver blocks and bricks as partial replacement to cement and clay. It is proposed to study the compressive strength, water absorption, efflorescence, abrasion resistance for the 10%, 20%, 35%, 35% with admixture and 75% replacement of cement and clay in paver blocks and in bricks. The properties of the components of sludge, the methodology of processing them, and the suitability of sludge in paver blocks and bricks had been discussed. The strength and other qualities of the paver blocks and bricks met the Bureau of Indian Standards.
