Effects of Changes in Resuscitation Temperature and Curing Method on the Compressive Strength of the Large Volume Mortar of Fly Ash after Application of the Resuscitation Material

소생재 도포 후 소생온도 및 양생방법 변화가 Fly Ash 다량치환 모르타르의 압축강도에 미치는 영향

In this study, we conducted a comparative analysis of the effects of resuscitation after the re-application of mortar with much FA replacement on the degree of resuscitation. Results When NaOH was applied to the top of the mortar where 90% of FA was replaced, and maintained for 24 hours, the degree of resuscitation at $40^{\circ}C$ was completely improved. However, when medium curing was carried out, it showed a higher degree of compression than water or lapping curing at 10 MPa in 28 days. The degree of resuscitation on the 28th day was revived from around 10% of the normal level to about 20~30%, and it was analyzed that it was difficult to achieve the OPC reduction by any method.
