PROBLEM TO BE SOLVED: To provide a lime-based expansive composition capable of adjusting hydration reaction time of lime itself with as few as manufacturing processes, capable of exhibiting higher expansion amount than conventional lime-based expansive materials.SOLUTION: There is provided an expansive composition containing lime dissolving Zn of 0.7 to 2.5 mass% in terms of ZnO as an essential component. There is provided an expansive composition containing lime dissolving Zn of 0.5 to 5.0 mass% in terms of ZnO with percentage content of the lime dissolving Zn of 0.5 to 5.0 mass% in terms of ZnO or 45 mass% or more, including 100 mass%.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調整せしめることができる生石灰系の膨張性組成物を提供する。【解決手段】 ZnをZnO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。ZnをZnO換算で0.5〜5.0質量%固溶する生石灰の含有率が45質量%以上(100質量%を含む。)であって、ZnをZnO換算で0.5〜5.0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
