Energy Consumption in Production of Concrete

Aug 28, 2017· The production of 1 m³ of concrete requires 2,775 MJ of energy. This energy comes mostly from oil burning, which generates CO2. 2.775 MJ of energy is produced by 0.37 barrels of oil. Saving concrete, e.g. by adopting appropriate building solutions, means therefore not only reducing fossil fuels consumption…

Concrete - Wikipedia

The overall embodied energy of concrete at roughly 1 to 1.5 megajoules per kilogram is therefore lower than for most structural and construction materials. Once in place, concrete offers great energy efficiency over the lifetime of a building. Concrete walls leak air far less than those made of wood …

Energy consumption reduction in concrete mixing process by ...

Mixing process plays a very important role in the concrete microstructure which defines the quality of the final product. The improvement of energy efficiency during this process can help to reduce energy consumption and production costs, without affecting product quality.

Concrete and Embodied Energy - Can using concrete be ...

Concrete is the most widely used building material in the world. There is now approximately 2 tonnes of concrete for each person on the planet earth. The small amount of embodied energy (carbon) in one tonne of concrete, when multiplied by the huge amount of concrete used, results in concrete …

Energy Efficiency and Saving in the Cement Industry ...

The main potential in reducing energy consumption and CO 2 emissions from cement/concrete production is in improvement of cement pyroprocessing. Pyroprocessing transforms the raw mix into clinkers. At present, about 78% of Europe's cement production is from dry process kilns, a further 16% of production is accounted for by semi-dry and semi-wet process …

A Concrete Energy Efficiency Solution - World Bank

A Concrete Energy Efficiency Solution. September 5, 2014. ... Cement — the key ingredient of concrete — is the world's most widely used building material. It's also the product of an energy-intensive process that accounts for about 5% of global greenhouse gases. These emissions threaten to increase as …

INDUSTRIAL CASE STUDY THE EMENT INDUSTRY

Energy Consumption Survey (MECS) data. Most of the usage is in the machine drive end use, associated with grinding, crushing, and materials transport. Cement industry natural gas consumption is concentrated in the process heating end use (about 90% of total gas consumption), which involves clinker production in large kilns.

This high energy consumption however leads to high carbon emissions, about 7% of the world's total carbon emissions. Cement production is an energy-intensive process consuming thermal energy of the order of 3.3 GJ/tonne of clinker produced. Electrical energy consumption is about 90 – …

Cement | Industrial Efficiency Technology & Measures

Cement production is an energy intensive process, with energy costs representing 20-40% of production costs (IEA, 2007. p. 145). Since 1990s, globally there has been a gradual reduction in the "clinker ratio" – the ratio of clinker to cement in the final product – which reflects in reduced specific energy consumption.
