METHOD FOR PRODUCING HYDRATED SOLIDIFIED BODY
To obtain a hydrated solidified body having excellent durability.SOLUTION: A method for producing a hydrated solidified body includes kneading and hardening a composition containing an aggregate containing a steel slag, a binder containing a blast furnace slag fine powder and water to obtain a hydrated solidified body. The steel slag includes steel slag fine aggregate which is a fine aggregate. The steel slag fine aggregate has a calcium ion concentration of 30 mg/L or more, in a test solution obtained by conducting a "Test by use as it is" as described in JIS K 0058-1:2005 "Test Methods for Chemical Substances in Slags - Part 1: Method for Testing Elution Amount"; and a mixing amount of the steel slag fine aggregate is 800 kg/m3 or more.SELECTED DRAWING: None
【課題】耐久性に優れる水和固化体を得る。【解決手段】製鋼スラグを含む骨材と、高炉スラグ微粉末を含む結合材と、水とを含有する組成物を混練し、硬化させることにより、水和固化体を得て、上記製鋼スラグは、細骨材である製鋼スラグ細骨材を含み、上記製鋼スラグ細骨材は、ＪＩＳ Ｋ ００５８－１：２００５「スラグ類の化学物質試験方法－第１部：溶出量試験方法」に記載された「利用有姿による試験」を実施することにより得られる検液中のカルシウムイオン濃度が３０ｍｇ／Ｌ以上であり、上記製鋼スラグ細骨材の配合量が、８００ｋｇ／ｍ３以上である、水和固化体の製造方法。【選択図】なし
