Expert cautions building industry against using cement

30 August 2006, Published under Cement News

The Malaysian construction industry must come up with a ‘greener’ alternative for cement because producing a tonne of cement causes an equal tonnage of carbon dioxide to be released into the atmosphere.  This in turn results in a sharp rise in greenhouse gas emission, said an engineering expert from Curtin University of Technology.
