Sampling and samplepreparation of primary and secondary materials

Abstract niet beschikbaarThe joint research project 'Environmental implications of useful applications of primary and secondary materials to be used on or in the ground' was carried out by four institutes i.e. RIVM, ECN, TNO and INTRON. In this research project an estimation is made of the environmental implications when primary materials (natural materials) are replaced by secondary materials (waste materials) in road constructions and building materials. Moreover the results will be used in order to contribute to the normalization of the application of secondary materials. This report concerns the sampling and sample preparation of 21 secondary and 15 primary materials. The sampling and sample preparation were carried out by the Department of Inorganic Chemistry of the National Institute of Public Health and Environmental Protection (RIVM). The samples were characterized macroscopically by the Foundation Materialenbank Nederland.DGM/
