Outline of Final Research Achievements

This study focused on the production of waterless lunar concrete. Sulfur concrete with the several additives such as simulated regolith and shot metallic fibres were used to improve the compressive strength and the flexural strength of the waterless lunar concrete. After the 3 years research of the waterless lunar concrete, the results showed the possibility of the waterless lunar concrete production. The optimum sulfate content and the optimum regolith addition to the waterless lunar concrete were found to improve the compressive strength and the flexural strength. It is found that the short metal fibre improves the flexural strength of the waterless lunar concrete with the addition of 2 to 6 % of the fibre.
This study propose the fundamental lunar base construction concept with applying the method of construction of Roman structure such as Roman aqueduct and dome structure using with the waterless small lunar concrete blocks.
