The cement suitable for the Autoclaved aerated concrete (AAC) was developed. The cement in which C3S, fineness (Blaine), and hemihydrate/gypsum (H/(H+G)) changed was produced experimentally. Using this cement, the effect of the cementitious property on the viscosity of the AAC slurry and the hardening of the AAC green cake was clarified. Though H/(H+G) influences viscosity, C3S and Blaine do not influence. On the hardening, it quickens, as C3S is more abounding, as Blaine is higher, as H/(H+G) is lower. The characteristic of the cement suitable for AAC consists like the following; a) HC with many C3S is made to be a base. b) The Blaine is desirable about 3800. c) Hemihydrate and gypsum are coexistence. The adaptability was confirmed by the factory scale test.
