NASA mixed cement aboard the space station; it hardened with strange stripes and highly porous structures that may affect its strength

Astronauts on the International Space Station conducted a unique experiment blending cement in microgravity. This innovative study seeks to explore the potential for building habitats on the Moon and Mars. Initial results indicated that the cement displayed distinctive porosity and striations, which are results of the weightlessness environment, contrasting greatly with the hardening process on Earth.
