The challenge of making concrete greener—reducing its sizable carbon footprint without compromising performance—is just like the world's most ubiquitous manufactured material—hard! http://phys.org/news284282851.html Technology Thu, 04 Apr 2013 08:28:23 EST news284282851 (Phys.org) -- While the largest contributor to anthropogenic greenhouse gas emissions is the power industry, the second largest is the more often overlooked cement industry, which accounts for 5-6% of all anthropogenic CO2 emissions. For every 10 kg of cement produced, the cement industry releases a full 9 kg of CO2. Since the world consumes about 3 trillion kg of cement annually, this sector has one of the highest potentials for CO2 emission reductions. But while processes are being explored to sequester the CO2 from cement production, so far no process can completely eliminate it. http://phys.org/news253254865.html Chemistry Tue, 10 Apr 2012 06:10:01 EST news253254865 Emissions of carbon dioxide (CO2) from fossil fuels and the cement industry scaled a record high in 2010, rocketing by 5.9 percent over 2009 in a surge led by developing countries, scientists reported on Sunday. http://phys.org/news242274620.html Space & Earth Mon, 05 Dec 2011 02:30:57 EST news242274620 Concrete is one of the most extensively used materials worldwide -- on average, more than two tons per year of the rock-like stuff is produced for every man, woman and child on Earth, making its use second only to water. And that vast amount of new concrete is responsible for somewhere between 5 and 10 percent of global greenhouse gas emissions, making it a significant target for improvements. http://phys.org/news233814046.html Space & Earth Mon, 29 Aug 2011 05:21:27 EST news233814046
