Sustainability Issues and Concrete Technology
The February 2007 report issued by the International Panel on climate Change (IPCC) has stated in no uncertain terms that global warming is no longer an issue that has to be debated. According to the report, global wanning is here, and drastic actions are needed for the long-term sustainability of our environment. It is in this context that this paper discusses the role of supplementary cementing materials as partial replacement for cement in concrete in reducing greenhouse gas emissions. Primary emphasis is on the use of high volumes of fly ash in concrete because this is available in huge quantities worldwide, and this vast supply will continue to be available at least up to the year 2050. Other supplementary cementing materials discussed include granulated, blast-furnace slag, rice-husk ash, silica fume and metakaolin. The paper is concluded by referring to the tradable emission rights, and the role of developing countries as regards to the CO2 emissions and sustainability.
