How concrete is made - material, manufacture, making, how to

Aggregates are pre-blended or added at the ready-mix concrete plant under normal operating conditions. The mixing operation uses rotation or stirring to coat the surface of the aggregate with cement paste and to blend the other ingredients uniformly. A variety of batch or continuous mixers are used.

Carbon Dioxide (CO2) Emissions of Concrete

2 from Concrete Constituents (2) Aggregates • ggregates ave a very low embodied CO 2 compared to Portland cement and contribute only 3% to the total for reinforced concreteonly 3% to the total for reinforced concrete. • Transportation of the aggregate to the batching plant and to site accounts for most CO 2 emission.

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, but also pollutant emissions.
