Green Concrete

Cameron Monroe's critique of my article on "green concrete" is valuable. Mr. Monroe refined and improved several details of the industrial chemistry of concrete.

He also illustrated how lucky we are here in eastern Ontario to have so many well-informed folks among us. Because we are able to discuss vital environmental relationships we can learn to fit ourselves in, as we must. Mr. Monroe made clear that the concrete industry was aware of and made changes to improve its influence on atmospheric carbon dioxide before the issue was well-known.

By providing a forum for such discussions, the News brings the issues to the attention of many readers.
