At present, about 33 billion tonnes of concrete are produced each year, and the cement used in concrete is responsible for five percent of total anthropogenic CO2 emissions.
The environmental impact assessment s for ready-mixed
concrete in Austria are calculated using Life Cycle Assessment. For this, 113 mixes from seven ready-mixed concrete companies, which produce around 40% of the ready-mixed concrete used in Austria, were reported.
In order to quantify the uncertainties in the background data, the Monte Carlo simulation method is used.
