Dawlish Sea Wall programme make use of low-carbon concrete

摘要

New low-carbon concrete being used on Network Rail's coastal protection scheme in Devon is predicted to save 1,130 tonnes of carbon dioxide compared with traditional concrete, reducing the project's carbon impact by two-thirds. The concrete (supplied by Hanson UK) makes use of a by-product created in the manufacture of steel to replace a large proportion of the cement which would otherwise be needed. Traditional concrete accounts for 7% of global carbon emissions worldwide (1.5% in the UK), due to the energy-intensive processes involved in making cement.
