A 'Greener' Take on Grey Concrete
Date posted: 24 January 2011
The grey concrete of our modern cities has a little known environmental cost which makes it far from 'green', a construction expert will tell an audience at the University of Derby's Enterprise Centre tomorrow (Tuesday January 25).
The heating of materials and chemical reactions involved in producing a tonne of cement (using Portland cement, an ingredient in almost all concrete) can release up to 900kilogrammes - or nine-tenths of a tonne - of polluting carbon dioxide gas emissions into the atmosphere; says Professor Peter Claisse, Professor of Construction Materials at Coventry University.
He will give a free presentation on Sustainable Concrete for the Midlands branch of the UK's Concrete Society at the University's Enterprise Centre in Bridge Street, Derby, from 6pm tomorrow (Tuesday).
The University's centre is the headquarters of its business-to-business arm, University of Derby Corporate; which runs certified courses for the concrete and construction industry, in partnership with trade bodies such as the Concrete Society.
Professor Claisse, the author of more than 100 publications in journals and conferences, has researched the environmental aspects of construction; including the use of waste materials in construction and waste containment.
His 45 minute talk will look at the various different, and more environmentally friendly, ways of producing construction grade concrete.
Professor Claisse said: "Replacing cement with by-product minerals, such as ash from power stations or slag from steel making, is one of the best ways to achieve an immediate reduction in the world's carbon footprint."
