With cooling tests on polypropylene fiber reinforced concrete and plain concrete that were initially subjected to different heating temperatures, the change of mechanical properties including mass loss, uniaxial compressive strength and microstructure were analyzed. The results show that the compressive strength of concrete tend to decrease with an increase in temperature. After experiencing high temperatures, the internal fibers of the polypropylene fiber reinforced concrete melted and left a large number of voids in it, thereby deteriorating the mechanical properties of concrete.

This paper presents the results of an experimental research designed to investigate the dynamic mechanical properties and constitutive model of fiber reinforced concrete (FRC), including steel fiber reinforced concrete (SFRC) and polypropylene fiber reinforced concrete (PFRC) under fast loading. Experimental results are achieved by using the electrohydraulic servo loading test method, implying that the dynamic mechanical properties of PFRC and SFRC, such as peak stress, peak strain, and toughness, are positively affected by strain rate. The experimental elastic modulus test results of FRC with different fiber contents indicate that the elastic modulus is positively affected by polypropylene or steel fibers and increases with the increment of fiber content. Finally, the experimental stress-strain curves obtained in the MTS electrohydraulic servo system test are fitted by a damage dynamic constitutive model of FRC. The good fitting with experimental results proves that the model could be appropriate to describe the dynamic mechanical properties of FRC.

Polypropylene Fiber Reinforced Concrete

The Steel-polypropylene fiber reinforced concrete take full advantage of steel fiber’s macro-scale crack resistance function on the concrete as well as the polypropylene fiber’s micro-scale crack resistance and toughening effect on the concrete matrix. In this paper, the three kinds of concrete specimens including plain high-strength concrete, steel fiber reinforced concrete and steel-polypropylene fiber concrete are selected for a flexural toughness experimental study, their compressive strength and deformation performance are analyzed, and their toughness index are investigated with ASTM-C1018 and PCS(post-crack strength) method. The results show that steel-polypropylene fiber reinforced concrete has better strength and toughness property as well as deformation performance.
