The paper analyses the properties (chemical and mineral composition, microstructure, density, etc.) of recycled tannery sludge (TS) and the possibilities for using it in cement mortar mixture. Mortar specimens containing 3–12% of tannery sludge by weight of cement and 3–9% of tannery sludge by weight of sand were tested. Flowability, density, ultrasonic pulse velocity (UPV), flexural and ...
Solid waste generation from tannery process is estimated as 6 × 10 9 kg per year (Rajamani et al., 2009). With the quick development of economy, the social awareness increases more to the health care and the ecology. The new legislations regarding leather manufacture drive the leather production more ecological as well.
