Gypsum hardened body
The present invention provides a hardened gypsum body and a method for manufacturing the same, in which the strength of the hardened gypsum body can be improved by controlling the coefficient of variation of the bubble diameter in the hardened gypsum body having the same density and the same average bubble diameter and containing bubbles, and a method for manufacturing the same. The gypsum hardened body according to the present invention contains bubbles, the density of the gypsum hardened body is 0.4 g/cm3 or more and 0.8 g/cm3 or less, the average bubble diameter in the gypsum hardened body is 200 [mu] m or more and 600 [mu] m or less, and the coefficient of variation of the bubble diameter is 0.30 or more and 0.48 or less.
本发明提供石膏硬化体及其制造方法，在含有气泡的相同密度、相同平均气泡直径的石膏硬化体中，通过控制气泡直径的变异系数，能够提高石膏硬化体的强度。本发明的石膏硬化体含有气泡，所述石膏硬化体的密度为0.4g/cm3以上且0.8g/cm3以下，所述石膏硬化体中的平均气泡直径为200μm以上且600μm以下，气泡直径的变异系数为0.30以上且0.48以下。
