to high temperatures in cement kilns . The Cambridge breakthrough saw scientists ‘ piggyback ’ on the heat generated by another heavy industry : steel recycling .
In steel recycling , chemicals are added that float on the surface of the molten metal , to prevent it reacting with the air and creating impurities , known as slag . The scientists discovered that the composition of used cement is almost identical to the slag used in electric arc furnaces .
Steel furnaces key to electric cement process They are currently trialling the electric cement process in an electric arc furnace at the Materials Processing Institute in Middlesbrough .
Partners in the project include Balfour Beatty , AtkinsRéalis , Tarmac , Celsa , Day Aggregates , the University of Cambridge and the Materials Processing Institute . Spanish company Celsa Group – a multinational group of steel companies
