Characterization and Utilization of ETP Sludge of an Automobile Industry for Development of Construction Product
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 2
Abstract
Laboratory scale studies were carried out for partial utilization of ETP sludge generated from an automobile industry for the development of building products. The chemical properties were determined using XRF show that it is organic and hazardous in nature as it contain phosphate apart from heavy metal ions. Various percentage of ETP sludge (8-15 %) have been used with cement and aggregates for development of road paving blocks by vibro-compaction method. The testing of paving blocks have been carried out for compressive strength and water absorption. It is observed that mixes having 10-11 % of ETP sludge and 22.5- 25.0 % of cement give compressive strength of more than 20 MPa and water absorption less than 6 % and were recommended for paving blocks manufacturing. The results of TCLP studies for recommended mixes show that leaching of heavy metal ions (Cr and Ni) in acidic medium are under the permissible limit of USEPA.
