Study of Mechanical Properties and Development of Concrete Using Sludge from Textile Industry

The interest in the use of industrial waste, such as sludge, has grown as an alternative both to reduce the volume of this environmental liability as in getting a product to be used in construction. This work aims to study the incorporation of waste textile sludge in concrete. The textile sludge was dried, in an oven lab, at 110oC for twenty-four hours and milled in a grinder to acquire adequate granulometry. Samples were prepared for compression strength and water absorption, the ratios 1:2, 1:3, 1:4 and 1:5 with sludge levels of substitution of 3%, 5% and 7% with 7, 28 days of curing. The results showed a tendency to increase the water absorption with increasing amount of textile sludge and decrease one with increasing cure time. Thus for compressive strength decreased with increasing content of aggregates and content of this sludge, according to the following increasing order 1:5
