Effects of Improving Durability of Concrete by AQUA CURTAIN Curing and Its Application m Development of the New Wet Curing Method

We report a wet curing system developed and made suitable for practical application to curing the interior and verticalconcrete surfaces of tunnel linings after the formwork has been removed. In this system, air is evacuated from the gap between the curing sheet and the concrete surface to create a close contact, and by supplying water to the space between the contacting surfaces, a water film is formed over the concrete surface. This enables the wet curing of vertical concrete surfaces and interior surfaces of tunnel linings after the formwork has been removed, a process that has to date been difficult. In this paper, the effects of wet curing on improving the durability of concrete are verified, and examples of the application of wet curing to actual structures are presented.
