Cement is considered a climate killer because of its energy-intensive production, but the building material has more to offer than expected. American researchers are working on ways to store electricity with concrete.
There are also good guys and bad guys in construction. Wood, for example, is one of the environmentally friendly building materials. Concrete is considered a bad guy. Above all, cement, which combines with water and aggregates such as sand or gravel to form concrete, is a climate killer. The consumption of concrete has multiplied worldwide. The material can hardly be dispensed with – for example in bridge construction. Office buildings and hospitals are also often built with it. This has economic, sometimes constructive, sometimes just lazy thinking reasons, at least the world is finding it difficult to do without concrete as an addictive substance in modern construction.
