Waste materials utilization as value-added materials and micro, nanoparticles inclusion is gaining huge attention. The sludge generated from the textile industry constitutes a high toxic compound and hazardous in nature. Currently, large quantities of solid sludge remain unattended and undisposed in various effluent plants, waiting to be disposed of at the landfills. In this study, the waste sludge generated from the textile industry was processed and reused as a substitute for cement material. The specimens prepared from the textile waste sludge along with nanoparticles were tested for durability and mechanical properties. The usage of textile sludge decreases the strength properties marginally until a replacement level of 10%. Beyond the addition of 10% textile sludge waste reduces the strength and durability properties significantly. Textile waste sludges were replaced for cement of varying proportions, i.e., 2.5%, 5%, 7.5%, 10%, 15% and 20%. The addition of alumina nanoparticles has dual effects, enhances the hydration properties and also acts as a filler material. The formation of calcium silicate hydrate gel was improved significantly due to the utilization of nano alumina. The optimum amount of alumina nanoparticles observed from the previous studies was found to be 3% by weight of cement due to high durability and mechanical properties. The combination of 10% textile waste sludge along with 3% nano alumina blended cement concrete leads to enhanced strength and durability characteristics as compared to all other concrete specimens and it was found to better eco-friendly construction material.
