CURING METHOD OF CEMENT MOLDED BODY
To provide a curing method of a cement molded body that can suppress the cracks due to the difference between the temperature of the cement molded body after accelerated curing and the open-air temperature (temperature cracks).SOLUTION: This is a curing method of a cement molded body accelerate-cured by heating the cement molded body formed by molding a kneaded product made by kneading a cement composition containing cement and water, in which the difference ΔT between the highest temperature T when accelerate-curing the cement molded body and open-air temperature Ta meets the following formula (1), ΔT≤26.6+1.27×Ta-26.3×t...(1)(ΔT=T-Ta)(t is the smallest dimension of the cement molded body).SELECTED DRAWING: None
【課題】促進養生後のセメント成形体の温度と外気の温度との差に起因して生じるひび割れ(温度ひび割れ)を抑制することができるセメント成形体の養生方法を提供することを課題とする。【解決手段】セメントを含むセメント組成物と水とが混練されてなる混練物が成形されることで形成されるセメント成形体を加熱することによって促進養生するセメント成形体の養生方法であって、前記セメント成形体を促進養生する際の最高温度Tと外気の温度Taとの差ΔTが下記(1)式を満たすセメント成形体の養生方法。ΔT≦26.6+1.27×Ta−26.3×t・・・(1)(ΔT=T−Ta)(tはセメント成形体の最小寸法である)【選択図】なし
