A 3-year project has been underway in Finland entitled "Environmentally-friendly and durable concrete." The project aims are similar to the EU CONLIFE project, but the research is done with local Finnish materials and with more normal strength concrete. The project's main aim was to make durable concretes that are environmentally-friendly and economically feasible. Additional goals include making comparisons between various frost-test methods, correlating lab and field performance, and providing guidelines for industry that are in agreement with Kyoto Protocol expectations. Testing was done on 19 mixtures designed as normal strength concrete (30-60 MPa) containing up to 60% fly ash and 70% blast furnace slag. In some cases a more environmental approach of using crushed aggregates was done to replace natural material. Laboratory and field station tests were conducted, along with coring from existing structures and making applied tests in local factories. This paper provides an overview of the project results and focuses on some of the research that has been done using fly ash, slag and crushed aggregate in roofing tiles at Lafarge Tekkin Oy.
