Effects of vacuum and other dry environments on properties of hardened mortar are discussed aiming at studying feasibility of lunar concrete. Mortar specimens cured in water for first several days were exposed to various dry environments which include; (1) a vacuum, (2) furnace dry at 110°C for 24 hours immediately before strength tests, (3) air dry at 20°C and 60% R. H., and (4) continuous furnace dry at 110°C. Weight losses and strength gains caused by the drying effect were observed for most of the dried specimens. Since the vacuum dried specimen showed the largest strength gain among these specimens, it was expected that well-cured mortar could be used in a vacuum environment.
