A set of temperature-controlling system adapted to high temperature split Hopkinson pressure bar (SHPB) experiments is developed and presented. Using this high temperature SHPB system comprised of a temperature-controlling system and a general Ø100 mm SHPB apparatus, the dynamic mechanical properties of concrete are investigated at 20, 200, 400, 600, 800 and 1 000 ℃, respectively. The experimental results show that the temperature-controlling system composed of a box preheating furnace and a tube real-time heating device is convenient to operate and can improve efficiency greatly, and the sample assembly method is simple and feasible; the temperature variance of sample and the local temperature rising of pressure bar due to heat conduction can be ignored, and the experimental technique is reliable. Temperature effects on dynamic mechanical properties of concrete at high temperature are obvious. With temperature increasing, the average strain rate and dynamic peak strain increase gradually, and the dynamic stress-strain curves exhibit plastic properties; moreover, the dynamic compressive strength rises at first and then falls.
