Take a look inside the box and join ESA astronaut Matthias Maurer from a very special perspective as he supports the @DLR Mason/Concrete Hardening experiment.
The Concrete Hardening experiment investigates the behaviour of various concrete mixtures containing cement and sand or simulated ‘Moon dust’ combined with water and various admixtures. On Earth, higher density components tend to move downward but in weightlessness they are likely to be more evenly distributed.
Researchers will analyse the concrete mixed by Matthias in space for strength, bubble and pore distribution as well as crystal structures, comparing this to ground samples. Their findings will facilitate the development of new, improved concrete mixes that could be used to construct habitats on the Moon or Mars and build more sustainable housing on Earth.
