AGING METHOD OF SLUG, MANUFACTURING METHOD OF CIVIL ENGINEERING MATERIAL, AND HYDRATION ACCELERATOR FOR AGING TREATMENT OF SLUG
To provide an aging method of slug capable of shortening an aging treatment for expansion suppression of the slug, by effectively accelerating hydroxylation (hydration) of the slug, when aging treating the slug containing free CaO or free MgO.SOLUTION: An aging treatment for hydrating free CaO and/or free MgO is performed with a hydration accelerator made of at least one or more kinds of hydration accelerators selected from NaOH, KOH, NHcontacted with the slug containing free CaO and/or free MgO. Due to the hydration accelerator working as a catalyst, the hydroxylation (hydration) of the free CaO and/or free MgO in the slug can be effectively accelerated to be able to shorten an aging interval.SELECTED DRAWING: Figure 1
【課題】遊離ＣａＯや遊離ＭｇＯを含有するスラグをエージング処理する際に、スラグの水酸化（水和）を効果的に促進させることで、スラグの膨張抑制のためのエージング処理を短期間で行うことができるスラグのエージング方法を提供する。【解決手段】遊離ＣａＯ及び／又は遊離ＭｇＯを含有するスラグに対して、ＮａＯＨ、ＫＯＨ、ＮＨ３の中から選ばれる１種以上からなる水和促進剤を接触させた状態で、遊離ＣａＯ及び／又は遊離ＭｇＯを水和させるエージング処理を行う。水和促進剤が触媒として働くことにより、スラグ中の遊離ＣａＯ及び／又は遊離ＭｇＯの水酸化（水和）を効果的に促進させることができ、エージング期間を短縮化できる。【選択図】図１
