Abstract
Growing population and life quality, both leads to high consumption of resources. High rate of consumption of resources generates a lot of waste materials. Improper management of waste materials causes various environmental problems. Textile Industries plays an important role in economy of a nation but on the other hand it generates a lot of waste materials through various processes. Textile industries generate a large amount of solid waste and its disposal creates many problems related to human health and our environment. The production of concrete utilizing industrial waste can help in reducing these environmental problems. In the present study the textile mill sludge was used as a replacement of fine aggregates in concrete. Plasticizer was added in concrete to improve the workability of concrete. A total of 342 concrete specimens were prepared by partial replacement of fine aggregates with textile mill sludge (5%, 15%, 25%, 35%, 45% and 55%) and with plasticizer (0.5% and 1% by weight of cement). The workability of concrete was tested by compaction factor test immediately after preparing the concrete mixes whereas the mechanical properties of concrete were checked after 7,14 and 28 days. The durability of concrete was checked after 28 days. The obtained results indicates that the workability of concrete decreases from medium to low with increase in content of textile mill sludge. The addition of both textile mill sludge (25%) and plasticizer (1%) in concrete gives maximum compressive strength and shows good durability results. Use of textile mill sludge decreases the cost of concrete upto 18.73%.
