PROBLEM TO BE SOLVED: To provide a quick lime-based expansive material capable of obtaining a manufacturing process that is the same degree as that of a conventional quick lime-based expansive material and capable of developing an expansion amount higher than that of the conventional quick lime-based expansive material.SOLUTION: An expansive material in which when any one kind or two or more kinds selected from the group consisting of Co, Ni and Mn is expressed by R, in the expansive material having quick lime in which the R is dissolved as an effective component, an inclusion mole ratio of the R that constitutes the quick lime in which the R is dissolved and the quick lime (CaO) is, in terms of an oxide (RO) of the R, satisfies (RO/CaO)=0.01 to 0.05.SELECTED DRAWING: None
【課題】 これまでの生石灰系膨張材と同程度の製造工程で得ることができ、これまでの生石灰系膨張材より高い膨張量を発現することができる生石灰系の膨張材を提供する。【解決手段】 Ｃｏ、Ｎｉ及びＭｎの群から選ばれる何れか１種又は２種以上をＲとすると、Ｒが固溶した生石灰を有効成分とする膨張材であって、Ｒが固溶した生石灰を構成するＲと生石灰（ＣａＯ）との含有モル比が、Ｒを酸化物（ＲＯ）換算で、（ＲＯ／ＣａＯ）＝０．０１〜０．０５であることを特徴とする膨張材。【選択図】 なし
