Lunar and Martian Resources Utilization: Cement

The constituents of inorganic materials available on the Moon and Mars are similar to those on Earth. Calcium oxide concentrations, the primary factor for the production of portland cement, of these materials are substantially less than that of companion terrestrial materials. However, cementitious materials with desirable hydraulic characteristics can be produced with raw materials having a calcium oxide content of approximately 10% by weight. How lunar and Martian soils could be used to manufacture cement under extraterrestrial conditions is the subject of this paper.
