Agnirva Space Premier League - Expedition #31561: Concrete in the Cosmos: Student Research on Building Materials in Space

What happens when you mix concrete in space? Students at Faith Christian Academy in Coalinga tackled this question with the NanoRacks-Faith Christian Academy-Concrete Mixing Experiment. Aboard Expedition 29/30, astronauts mixed cement components in microgravity to see how the absence of gravity affects the curing and strength of concrete.

On Earth, gravity helps cement particles settle and bind, influencing the strength and structure of the final material. In microgravity, this dynamic changes, potentially leading to different porosity and bonding characteristics. Understanding these differences is crucial if we’re to build structures on the Moon or Mars someday.

Students compared space-formed samples to Earth-based controls, learning how construction materials behave in unique environments. This project helped lay the groundwork for extraterrestrial construction while giving students firsthand experience in space research.
