  2. Environmental impact of concrete - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    Concrete produced by carbonation curing also shows superior performance when subject to physical degradations, e.g., freeze-thaw damage, particularly due to a pore densification effect enabled by the precipitation of carbonation products [38] The vast majority of CO 2 emissions from concrete come from cement manufacturing. Therefore, methods to ...

  3. Cement kiln - Wikipedia

    en.wikipedia.org/wiki/Cement_kiln

    As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of kiln efficiency has been the central concern of cement manufacturing technology. Emissions from cement kilns are a major source of greenhouse gas emissions, accounting for around 2.5% of non-natural carbon emissions worldwide. [1]

  4. Cement - Wikipedia

    en.wikipedia.org/wiki/Cement

    A Chatham House study from 2018 estimates that the 4 billion tonnes of cement produced annually account for 8% of worldwide CO 2 emissions. [4] Nearly 900 kg of CO 2 are emitted for every 1000 kg of Portland cement produced. In the European Union, the specific energy consumption for the production of cement clinker has been reduced by ...

  5. Portland cement - Wikipedia

    en.wikipedia.org/wiki/Portland_cement

    Environmental concerns are the high energy consumption required to mine, manufacture, and transport the cement, and the related air pollution, including the release of the greenhouse gas carbon dioxide, dioxin, [citation needed] NO x, SO 2, and particulates. Production of portland cement contributes about 10% of world carbon dioxide emissions. [26]

  6. Concrete - Wikipedia

    en.wikipedia.org/wiki/Concrete

    The production of clinker, the main constituent of cement, is responsible for the bulk of the sector's greenhouse gas emissions, including both energy intensity and process emissions. [133] The cement industry is one of the three primary producers of carbon dioxide, a major greenhouse gas – the other two being energy production and ...

  7. Limestone Calcined Clay Cement - Wikipedia

    en.wikipedia.org/wiki/Limestone_Calcined_Clay_Cement

    The main components of LC3 cements are clinker, calcined clay, limestone, and gypsum. [24] [25] [26] The fresh concrete production involves synergetic hydration.[10] [27] Adding large amounts of calcined clay and ground limestone to the dry cement powder, [28] [29] when adding water to the mix for making concrete, cement and additives start to hydrate and the soluble aluminates released in ...

    The EPA’s new carbon dioxide rules would require carbon capture or green hydrogen to reduce greenhouse gases at new natural gas plants. EPA wants power plant CO2 emissions cut to slow climate ...

  9. Calcination - Wikipedia

    en.wikipedia.org/wiki/Calcination

    Calcium oxide is a crucial ingredient in modern cement, and is also used as a chemical flux in smelting. Industrial calcination generally emits carbon dioxide (CO 2). A calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature processing (550–1150 °C, or 1000–2100 °F) within a controlled ...
