Experimental Study on Flexural Toughness of Steel-Polypropylene Fiber Reinforced Concrete

Abstract:

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.
