the lunar rover at the moon's south pole hasn't found ice yet, but it has found sulfur, aluminum, calcium, iron, chromium, titanium, manganese, silicon, and oxygen. No hydrogen though

Sulfur is of particular interest based on research that indicates it could be used to make concrete, rather than relying on Portland Cement, whose ingredients are likely to be less accessible.

When quantities of Portland cement were first imported to the United States in the 1880s, its principal use was in the construction of sidewalks. Its name is derived from its similarity to Portland stone which was quarried on the Isle of Portland in Dorset, England. It was named by Joseph Aspdin who obtained a patent for it in 1824.

Portland cement is one of the lowest-cost materials widely used over the last century. Concrete produced from Portland cement is one of the world's most versatile construction materials.

Portland cement had been imported into the United States, and in the 1870s, it was being produced near Kalamazoo, Michigan.

By the early 20th century, American-made Portland cement had displaced most of the imported Portland cement.
