How concrete is made
Cement manufacturing is the source of 5% of global CO2 emissions The cement industry is a natural producer of CO2: 60% of emissions are due to the transformation of raw materials at high temperatures (the "decarbonation" of limestone), 40% result from the combustion required to heat the cement ,...
Emissions from the Cement Industry
May 09, 2012· Cement Emissions The production of cement releases greenhouse gas emissions both directly and indirectly: the heating of limestone releases CO 2 directly, while the burning of fossil fuels to heat the kiln indirectly results in CO 2 emissions The direct emissions of cement occur through a chemical process called calcination...
