Reducing the Environmental Cost of Concrete

Carbon Friendly Cement

“There is a way to make our city streets as green as the Amazon Forest. Almost every aspect of the built environment from bridges to factories to tower blocks, and from roads to sea walls, could be turned into structures that soak up carbon dioxide – the main greenhouse gas behind global warming. All we need to do it is the change the way we make cement.”

The table on the left gives an indication of the sequestration capability of certain cement types

The below diagram outlines the science behind carbon sequestrating cement.
