GREEN CONCRETE - A LIFE CYCLE APPROACH

Cement and concrete have an important role to play in enabling Denmark to fulfil its obligation to reduce the CO2 emission by 21% of the 1990 level before 2012 as agreed at the Kyoto and the Bonn Conference. It is also possible to use residual products thus reducing the need to landfill these materials - while still maintaining a high concrete quality. The entire life cycle of a concrete structure has to be taken into account to obtain environmental improvements. This highlights the need for a united business effort. This has been achieved by the creation of the Centre for Green Concrete. New technology is developed for all phases in the design, construction and use of concrete structures including a demonstration road bridge. Results so far indicate that the environmental goals set up will be achieved. (A) For the covering abstract see ITRD E121772.
