Dataset of "Enabling Precise Process Control with Flow Rate Measurements for Concrete in Shotcrete 3D Printing"

This dataset includes the data of the paper "Enabling Precise Process Control with Flow Rate Measurements for Concrete in Shotcrete 3D Printing". Each file contains the recorded concrete weight and data of an execution of the same experimental plan as follows: The concrete pump was set to one of three specific revolution speeds. Air flow rate was set to 50 m3/h. The pump and air flow was started. While pumping, the air flow was reduced from 50m3/h to 40 m3/h and 30 m3/h each after about 30 seconds. Finally the pump and air flow was stopped. The files contain weight data of a scale located placed below the concrete srew pump and the weight data of the shotcrete nozzle. The name of the file indicates the number of the procedure which is connected to a specific pump setting. The table below marks the correlation between the file number and the pump setting.
