The concrete construction industry depends on environmentally demanding processes, such as mass consumption of energy and raw materials, and extensive transportation, thereby contributing significantly to global carbon dioxide (CO2) emissions. Globally, Portland cement production emitted 932 million metric tons of CO2 (MtCO2) in 2002, i.e. approximately 7% of all stationary CO2 sources. Typical emission rates between 1995 and 2005 varied from 0.6 to 1.0 kg of CO2 per kg of Portland cement. While alternatives to Portland cement exist, such as blended cements or low CO2-emitting cements, the demand for Portland cement continues to increase. In the production of 1 000 kg of Portland cement, 125 ℓ of fossil fuel and 118 kWh of electricity are consumed.
