Concrete Design Production

It may be fully carbon neutral in longer timeframes Concrete can absorb carbon dioxide and store it in a process commonly referred to as carbonation This may be viewed simply as an additional alternative loop of the complex carbon cycle Carbon dioxide may be absorbed by concrete in its many forms such as buildings bridges and pavements Get price
