Abstract

Concrete lining is at times adopted as part of the support members for mountain tunnels. In the case of concrete lining for road tunnels in particular, concrete lining with a 30 cm width is applied at a standard rate of 10.5mper two days, due to the characteristics of construction work. Because of this the curing time available for the concrete lining is between 15 to 20 hours, which makes securing a favorable quality difficult. A moisture curing system intended for concrete lining is developed in order to increase the quality with as short a curing period as possible. The moisture curing system uses negative pressure to adhere a curing sheet onto the surface of the lining, in order to circulate the curing water between the lining surface and the curing sheet to ensure that a wet condition is sustained. An experimental test of this system is conducted by curing a concrete lining for an actual road tunnel. As a result it was possible to ensure that moisture curing of the concrete lining was achieved. Furthermore, when the compression strength of the concrete was compared to verify the effectiveness of the moisture curing for the lining, it clarified that when compared to cases when moisture curing was not used (air curing), the compression strength was 2.0 to 2.5 times stronger.
