METHOD FOR MANUFACTURING GEOPOLYMER SOLIDIFIED BODY
To provide a method for manufacturing a geopolymer solidified body, capable of efficiently manufacturing a geopolymer concrete product having excellent strength and acid resistance.SOLUTION: A method includes: a first curing step of heating and curing a kneaded material in a formwork for a predetermined first curing time until the material has a predetermined demolding strength or more; and a second curing step of removing the formwork after the first curing time has elapsed, and then heating and curing the material until a predetermined second curing time has elapsed. Therefore, after strength is developed until demolding by the first curing step, acid resistance can be increased in the second curing step, thereby producing a geopolymer solidified body having sufficient strength and acid resistance for practical use. In this process, since the formwork removed after the first curing time has elapsed can be efficiently used to manufacture other geopolymer concrete products, the number of products manufactured using the same formwork can be increased, thereby improving productivity.SELECTED DRAWING: Figure 1
【課題】強度及び耐酸性に優れたジオポリマーコンクリート製品を効率よく製造することのできるジオポリマー固化体の製造方法を提供する。【解決手段】練り混ぜた材料を所定の脱型強度以上に達するまで所定の第１の養生時間だけ型枠内で加温養生させる第１の養生工程と、第１の養生時間が経過した後、型枠を外して所定の第２の養生時間が経過するまで加温養生させる第２の養生工程とを含むようにしたので、第１の養生工程により脱型までの強度を発現させた後、第２の養生工程において耐酸性を高めることができ、実用上十分な強度と耐酸性を有するジオポリマー固化体を製造することができる。その際、第１の養生時間が経過した後に取り外した型枠を他のジオポリマーコンクリート製品の製造に効率よく利用することができるので、同一の型枠による製造数を増やすことができ、生産性の向上を図ることができる。【選択図】図１
