| Abstract: | An experimental setup was developed for rapid heating up concrete based on the principle of microwave heating and concrete specimens were manufactured.Dynamic compression experiments were conducted for the manufactured concrete specimens by using a split Hopkinson pressure bar system at different temperatures.The experimental results show that temperature is the primary factor for influencing the dynamic compression mechanical performance of concrete at high temperature and strain rate is the minor factor.U... |
