EXPANSIVE COMPOSITION AND CEMENT COMPOSITION
To provide an expansive composition and a cement composition that suppress crack due to drying shrinkage and hydration heat generation from early stage of material age and has excellent neutralization resistance.SOLUTION: Provided is an expansive composition which contains a cement admixture and an expansive admixture, in which the cement mixture containing one kind of, or two or more kinds of non-hydraulic compound selected from a group consisting of γ-2CaO-SiO2, 3CaO-2SiO2, α-CaO-SiO2, and calcium magnesium silicate.SELECTED DRAWING: None
【課題】乾燥収縮と水和発熱によるひび割れを材齢初期から抑制しつつ、かつ、中性化抵抗性に優れる膨張組成物及びセメント組成物を提供する。【解決手段】γ－２ＣａＯ・ＳｉＯ２、３ＣａＯ・２ＳｉＯ２、α－ＣａＯ・ＳｉＯ２、及びカルシウムマグネシウムシリケートからなる群から選ばれる１種又は２種以上の非水硬性化合物を含むセメント混和材と膨張材を含有する膨張組成物。【選択図】なし
