| Abstract: | Based on the energy conservation law, the temperature increasing and decreasing differential equations of carbon fiber reinforced electric conductive concrete under electric heating are established and solved. Then the temperature variation curves during heating and cooling are achieved. The curves express comprehensively the effect of surface area of thermal losing, electric heating power output, and coefficients of convective and radiant heat transfer on the temperature variation regularity. The temperature increasing and decreasing curves are measured in laboratory and the experimental results are consistent with those computed by the temperature variation curves. |
