Article Preview

After 51 C40 HPC specimens with a size of 100mm×100mm×400mm were heated to 400°C, 600°C, 700°C, 800°C for 2 hours, and 300°C and 500°C for 1h, 2h, 3h, 4h, 5h separately, cooled naturally and placed for 24 hours, the flexural strength were experimented respectively. Subsequently, the effect of high temperature and its acting time on the flexural strength of HPC and the variation discipline were analyzed; meanwhile, the degradation mechanism of HPC after elevated high temperature was discussed.
