Implementing environmentally-friendly and durable concrete to Finnish practice

Producing durable concrete that is environmentally-friendly has been the goal of recent Finnish research. Extensive testing was done on about 40 mixtures containing up to 10 % silica fume, 60 % fly ash, and/or 70 % blast furnace slag. Laboratory and field station tests were conducted, along with coring from existing structures and making applied tests in local factories. Models were developed to assess deterioration tendencies and recommendations were provided for industry. This paper provides an overview of the project results and shares how some of the research results have been implemented by Finnish industry.
