Reducing CO2 emission with new types of concrete

28. 05. 2022 | 19.00 Uhr - 19.30 Uhr

It is flexible to use and ubiquitous, extremely stable, long-lasting and easy to manufacture: Concrete. The ingredients are available almost everywhere and are still relatively inexpensive. But concrete contributes an estimated seven percent of global anthropogenic CO₂ emissions. And a look into the future shows that it will become much more. China already consumed more cement, one of the main components of concrete, between 2010 and 2013 than the U.S. did in the entire 20th century. The construction boom in India is just getting started. And it is also beginning in Africa and will take on huge proportions. Because of its universally useful properties and the desire to use them, concrete is becoming the number one climate killer. That's why materials scientists are developing new concrete recipes. The goal: to find a building material whose production produces less CO₂ through the use of new additives, which is nevertheless stable and flexibly available for the building, living and life of the future. "Gut zu wissen" provides information about new concrete technologies, new building and living ideas, and how CO₂-saving construction is already taking place in developing countries.
