PROBLEM TO BE SOLVED: To provide a curing device of concrete which is capable of efficiently curing and hardening the concrete in a short time. SOLUTION: In the curing device 1, the concrete cast in a mold 4 is cured and hardened by sending heating steam S in a curing tank 2 housing the mold 4 in which the concrete is cast. In this case, the curing tank 2 is provided with a hot air circulating device 3 which takes out air in the curing tank 2, dries and heats the air and sends the air into the curing tank 2 again. Further, the curing tank 2 is provided with the hot air circulating device 3 which takes out the air in the curing tank 2 to exhaust or dries and heats the taken-out air to send into the curing tank 2 again. |
