Magnesium oxychloride cement composites filled with Martian soil simulant.

This contribution deals with design and development of magnesium oxychloride cement (MOC) composites for extraterrestrial application. For the design of the composite, Martian soil simulant MGS-1 was used as a filler, in order to form a composite, which uses materials available at the locality of application. The designed composite contained 5 wt. % of MGS-1 (relatively to the content of MgO) and was prepared with two types of raw MgO powder with different purity. Overall four types of MOC-based material were prepared, analyzed using multiple types of analytical methods and mechanical tests and compared with each other. The influence of the Martian soil simulant on the MOC matrix was assessed, showing the high potential of such material in its intended environment of application. [ABSTRACT FROM AUTHOR]
