The Environmental Impact of Recycled Concrete

2012-8-14  Carbonation presented in figure 1 is due mainly to the exposed area of crushed concrete which is higher at recycling facility yards or building sites than the interiors of buildings. The most marked difference in carbonation is in the first 4 months of demolished concrete. Concrete can absorb up to 68% of carbon dioxide released in concrete calcination, for a building service life of 100 years and subsequent recycling of this concrete. However, non-renewable energy resources used to crush and transport concrete to recycling plants do not allow high gains of carbonation. Steel structure recovered during crushing and separation operations of concrete contribute to the carbon cycle because steel recovered from structure can be recycled.
