Abstract
A national quality control standard for reclaimed concrete was published in Finland in 2001. The preparation work of the standard was ordered from VTT by the Finnish Federation of Environmental Enterprises. The standard specifies the basic requirements for a production control system, technical and environmental classification of crushed concrete products, technical and environmental properties to be monitored as well as sampling and monitoring methods. The properties to be monitored include leaching of Cd, Cr, Cu, Pb and SO42-, material purity, grain-size distribution, compression strength and frost susceptibility. If material is classified in environmental class 1, which may be used in unpaved constructions, the content of PAH and PCB shall also be investigated. The use of reclaimed concrete in road construction has grown considerably in Finland and its suitability as a substitute for natural minerals in earth construction has been proved in practice. Specified quality requirements and development of a quality control system give the producer the possibility to ensure that the material is produced in conformance to the relevant environmental and technical specifications.
