PROBLEM TO BE SOLVED: To provide a concrete placing management method and a concrete placing management system, by which concrete placing can be managed so that concrete can be surely placed in a concrete placing space densely. SOLUTION: Using a sensor 2 disposed above a concrete placing space 1b, the distance of a concrete face C1 displaced from a lower position to a higher position during the placing of the concrete C is measured. Using a calculation display device 3 that has received a measurement value output from the sensor 2, the height T1 of the concrete is calculated based on the measurement value and it is displayed in real time.
