Appraisal of Green Construction Material by Optimizing the Strength of Tannery Sludge Concrete

Tanning industries are emerging as economic contributor for developing countries with fifth position and largest among processing work in India. Due to the large production (144 million tons per year) and wastage (1.3 million tons per year) of leather products, it is mandatory to utilize the wastes generated in a proper way. In this work it is considered to use the tannery sludge as admixture and as replacement material of coarse aggregate to reasonable increase in composition for potential application in modern construction industry.
