급속양생 기술의 터널라이닝 콘크리트 적용

In this paper, tunnel lining concrete curing technology using microwave heating system is introduced. The curing time to reach the required compressive strength of 3MPa in order to remove the tunnel lining form was measured. The measured times were 4 hours with the heat curing system and 27 hours with the conventional curing system. Thus, it is concluded that the curing time of tunnel lining concrete can be reduced up to 85% with the adoption of microwave heating system.
