10 Advantages of Concrete as Construction Material | Why

The amount of energy required for production of concrete is low compared with steel. For plain cement concrete only 450-750 kWh/ton energy is required and that of reinforced concrete is 800-3200 kWh/ton. Production of structural steel demands 8000 kWh/ton or more to make which is almost 3-10 times the energy consumption. 5.

Energy Consumption in Production of Concrete

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.
