PROBLEM TO BE SOLVED: To provide a concrete secondary product curing control device with a post-curing control function for winter that can properly cope even in winter.SOLUTION: A concrete secondary product curing control device with a post-curing control function for winter comprises: a timer; a temperature information receiving part that receives temperature information from a temperature sensor detecting the temperature in a curing chamber; a calculation part for calculating a temperature gradient based on time information from the timer and the temperature information from the temperature information receiving part; a comparison part that compares the temperature gradient calculated by the calculation part with a preset value α; and a valve opening/closing part that opens/closes a valve arranged in steam supply piping supplying steam into the curing chamber. When the temperature gradient is larger than the value α, the valve is opened, and when the temperature gradient is less than the value α, the valve is closed.SELECTED DRAWING: Figure 1 |
