Potential technical challenges to decarbonizing cement and concrete production remain. For cement that incorporates a higher share of SCMs and alternative binding materials,

The United States has made a commitment to go back to the moon to stay in the early part of the next century. In order to achieve this objective it became evident to NASA that a Lunar Outpost will be needed to house scientists and astronauts who will be living on the moon for extended periods of time. A study has been undertaken by the authors and …
