Influence of Changing Production Conditions on Binding and Leachability of Heavy Metals Out of Clinker and Cement

Project: Research project

Project Details


The use of secondary raw materials (fly ash; residuals from industry, etc) as well as additional sources of energy such as old tires, contaminated oil, organic solvents, etc. for the production of cement clinker increases during the last years. Therefore the number and quantity of heavy metals in clinker increases and their binding and mobility is affected by this. In this research project the incorporation of heavy metals (chromium, vanadium, lead, copper, barium and others) in various clinker minerals, the changes of the properties of cement clinker (crystal structure, texture, etc) and the leachability of heavy metals is studied.
