Effects of High Temperature Maintenance Time and Curing Method on Compressive Strength of FA Large Volume Replacement Mortar after Application of Resuscitation Material

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

In this study, we conducted a comparative analysis of the effects of retention time and resuscitation method on the degree of resuscitation after reapplying mortar with much FA replacement. Results After applying NaOH to the top surface of 60 % FA-substituted mortar, the degree of resuscitation at $40^{\circ}C$ was high enough to increase the overall curing time, but there was no significant difference. However, with regard to the curing method, middle curing showed the greatest manifestation, followed by wrapping and underwater curing, but there was no significant difference. The resuscitation level on the 28th of the lumber was found to be revived to about 70~80 % at around 30 % without resuscitation.
