HARDENING METHOD OF WASTE GYPSUM
PROBLEM TO BE SOLVED: To provide a production method of a waste gypsum hardened body, and a hardening method of waste gypsum, capable of producing a hardened body having a remarkably high compressive strength by hardening the waste gypsum without re-firing it.SOLUTION: In a hardening method of waste gypsum, silicic acid-containing aqueous solution containing a compound shown by formula (I) HO-[Si(OH)-O]-H (I) (n is an integer of 1-10) and the waste gypsum are kneaded together. In a re-utilization method of waste gypsum, a hardened body having a remarkably high compressive strength can be produced not only by hardening the waste gypsum or gypsum dihydrate without firing but also by hardening hemihydrate gypsum.SELECTED DRAWING: None
【課題】廃セッコウを再焼成することなしに硬化せしめて、著しく高い圧縮強度を備える硬化体を製造することができる廃セッコウ硬化体の製造並びに廃セッコウの硬化方法の提供。【解決手段】式（Ｉ）ＨＯ−［Ｓｉ（ＯＨ）２−Ｏ］ｎ−Ｈ（Ｉ）（ｎは１〜１０の整数）で示される化合物を含有するケイ酸含有水溶液と、廃セッコウとを混練する廃セッコウの硬化方法。焼成せずして廃セッコウ又は二水セッコウを硬化し得るばかりではなく、半水セッコウを硬化すると著しく高い圧縮強度を備える硬化体を製造できる廃セッコウの再利用方法。【選択図】なし
