To a few of the samples, they also added a powdered clay mineral called metakaoline (MEH-tah-KAY-oh-leen). That means there will soon be a lot of construction in the country (which is about twice the size of the state of Delaware). They have good thermal and fire resistant. And while it may seem as though dealing with concrete is as simple as backing up one of those ubiquitous trucks and dropping the cement, there is a great deal of engineering, planning, and testing that occurs before the concrete is evenly mixed. "In addition, the harsh environment of space may be problematic for any inhabitant, but concrete could be the solution by providing the needed protection from cosmic .
