Mechanical Properties of High Performance Concrete after Exposure to ElevatedTemperatures

摘要

This research effort aims to characterize the residual mechanical properties ofhigh performance concrete (HPC) after being exposed to elevated temperatures. Residual mechanical properties of four different types of concrete were measured after being heated 450 deg C. The average compressive strength for these four types of concrete, before being exposed to elevated temperatures, ranged from an average of 40 MPa (6000 psi) to 100 MPa (15000 psi). Three of the concrete types are high performance concrete (HPC), and one represents conventional normal strength concrete (NCS).
