    Concrete as Solar Reflectance Material Americas Cement

    Concrete does a very good job of reflecting solar energy. That is the finding from a Portland Cement Association PCA study which measured the solar reflectance index SRI of 45 concrete mixes. Lighter colored materials such as concrete generally have a higher solar reflectance. They reflect heat from the sun and do not warm the air very much.

    How Does Clinker Cooler Reduce Cement Production Energy

    The main power consumption of a clinker cooler is its cooling fans. It usually takes 1.9-2.3 m 3 under standard conditions to cool 1 kg clinker from 1400 ℃ to 65 ℃ and the power consumption of the whole system is about 7 kWh. If the air consumption per kilogram of clinker cooling is reduced from 2 m 3 to 1.7 m 3 the air consumption efficiency will be 15 lower than that of other cement .

    Qamp;A Why cement emissions matter for climate change

    Sep 13 2018 A further 40 of cement emissions come from burning fossil fuels to heat kilns to the high temperatures needed for this calcination process. The last 10 of emissions come from fuels needed to mine and transport the raw materials. Therefore cement emissions depend largely on the proportion of clinker used in each tonne of cement.
