title = "Post-fire assessment of mechanical properties of polypropylene-fibered reactive powder concrete using non-destructive testing methods",
abstract = "Reactive powder concrete (RPC) is an advanced generation of concrete having superior qualities than traditional types of concretes. However, fire may severely affect its quality and strength. In this paper mechanical properties of RPC containing polypropylene (PP) fibers were studied experimentally after exposure to high temperature. The quality of concrete was also assessed by non-destructive testing (NDTs) such as ultrasonic pulse velocity (UPV) method and resonance frequency (RF) method. Dynamic elastic modulus has been determined by available equation from NDTs measurements. The results show that an initial increase in strength was observed up to 300℃. However, a gradual decrease in strength occurred for temperature higher than 300℃. Constitutive relationships have been proposed for structural strength assessment through NDTs.",
