摘要

The Industrial Revolution turned a new leaf in the economic growth of India, which is famous for its industries and agriculture. Notably, the textile industry, which is one of the major sectors, has had rapid growth throughout India in general and Tamil Nadu in particular. The government of India has earmarked seven hundred crore rupees in its twelfth five-year plan during 2012-2017 for the development of textiles to increase production at a large scale. For the largest production operations, the necessity arises for the treatment of effluents to be carried out jointly by companies or as individual industries. Apparently, the treatment of textile effluents generates sludge in bulk quantities. This poses a challenge for its disposal. So, attempts were taken to use the sludge as an affordable construction material. Sludge was collected from the effluent treatment plants of the textile industries located in the State Industries Promotion Corporation of Tamil Nadu (SIPCOT), Perundurai, which is popularly known as a commercial hub. To make a brick, materials like hypo sludge, textile sludge, quarry dust, fly ash, and gypsum were added in suitable proportion. The manufacture of bricks was done in accordance with Indian standard practice. Not only observations but also evaluations were made correctly. There was an increase in strength, which satisfied the criteria of durability, as hypo sludge content was increased. All the combinations that were formulated for the production of brick satisfy Bureau of Indian Standards (BIS) requirements.
