The Analysis on how the Polypropylene Fiber Reinforced Concrete Works
In this paper, we take the polypropylene fibers in concrete mechanisms as the starting point, then analysis the impact of the following four effects on the properties of polypropylene fiber concrete: thickening effect, toughening effect, crack resistance effect, load transfer effect, from which was out the following useful conclusions: the rate of low-doped fiber reinforced concrete with polypropylene fiber content increases, can further reduce the spacing between fibers in concrete to enhance crack resistance effect, the intrinsic quality of concrete with high resistance to dynamic load characteristics of sensitivity is also can be improved, and after the concrete has better crack toughness, with due extension of time to eliminate vibration molding concrete thickening effect on the strength of the adverse effects; incorporation activity of mixed materials.
