Title:
セメント成形体の養生方法
Document Type and Number:
Japanese Patent JP7049592
Kind Code:
B2
Abstract:
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
