PROBLEM TO BE SOLVED: To provide a caustic lime-based expansive composition capable of adjusting hydration reaction time of caustic lime itself with manufacturing processes as small as possible so that higher expansive amount can be developed than conventional caustic lime-based expansive materials.SOLUTION: There is provided an expansive composition containing caustic lime solid eluting Mg of 0.7 to 2.5 mass% in terms of MgO as an active ingredient. There is provided an expansive composition having caustic lime percentage content of 45 mass% or more (including 100 mass%) and containing caustic lime solid eluting Mg of 0.7 to 2.5 mass% in terms of MgO as an active ingredient.SELECTED DRAWING: None
【課題】これまでの生石灰系膨張材よりもより高い膨張量を発現させることができるように生石灰自体の水和反応時間を、できるだけ少ない製造工程数で行えるよう調整せしめた生石灰系の膨張性組成物を提供。【解決手段】ＭｇをＭｇＯ換算で０．７〜２．５質量％固溶する生石灰を有効成分とする膨張性組成物。生石灰含有率が４５質量％以上（１００質量％を含む。）であって、ＭｇをＭｇＯ換算で０．７〜２．５質量％固溶する生石灰を有効成分とする膨張性組成物。【選択図】なし
