Abstract :
The variation of residual compressive strength in the process of High-temperature of C40 high-performance concrete was studied in the paper, compared with the variation after natural cooling,the differences were found and analyzed. The relationship of them were fitted by using the ORIGIN7.5 software the results showed that HPC residual strength fluctuated significantly when the temperature was between 300°C and 400°C, the residual compressive strength after natural cooling rose less obviously than in the process of Hgh-temperature. Under the same heating temperature condition, the residual compressive strength in the process of High-temperature was slightly higher than after natural cooling.
