CORE MATERIAL, GYPSUM BOARD AND METHOD FOR PRODUCING CORE MATERIAL
To provide a core material or the like that prevents the problem of difficulty in screwing in a screw, while maintaining a high specific gravity.SOLUTION: A core material is predominantly composed of gypsum. In the core material, the relationship between a compression strength y (N/mm2) and a specific gravity x satisfies the following formula (1). (1) y≤0.9393×e2.6372x-0.3.SELECTED DRAWING: Figure 3
【課題】比重を高い状態に維持しつつビスが入り難いという問題が生じにくい芯材等を提供する。【解決手段】石膏を主成分とする芯材であって、圧縮強度ｙ（Ｎ／ｍｍ2）と比重ｘとの関係が、以下の式（１）を満たす、芯材。（１）ｙ≦０．９３９３×ｅ2.6372x−０．３【選択図】図３
