Concrete Design Production - Portland Cement Association

Concrete is a mixture of two components: aggregates and paste. The paste, comprised of cement and water, binds the aggregates (usually sand and gravel or crushed stone) into a rocklike mass as the paste hardens. A properly proportioned concrete mix possesses acceptable workability of the freshly mixed concrete and durability, strength, and ...

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.
