Abstract


With the emergence of fiberreinforced concrete and the development of the situation, Fiber reinforced concrete has become a hot area of research. Researchers at home and abroad in the fiberreinforced concrete material properties and applications have done a lot and achieved fruitful results. However, the current study focused on the physical and mechanical properties of fiberreinforced concrete.And for its durability is still a significant weakness of the study, in particular, a variety of fiberreinforced concrete comparative study of the longterm performance is more rare. For this problem, this paper has done a study of the following:A base of concrete, steel fiber reinforced concrete, alkaliresistant glass fiber reinforced concrete, polypropylene fiber reinforced concrete comparison of the permeability test, found that fiberreinforced concrete permeability was significantly higher than the base concrete, concrete fiber, polypropylene fiber reinforced concrete anti the best permeability, followed by alkaliresistant glass fiber reinforced concrete, steel fiber reinforced concrete for the worst.A base of concrete, steel fiber reinforced concrete, alkaliresistant glass fiber reinforced concrete, polypropylene fiber reinforced concrete comparison of the frost resistance test, found that fiberreinforced concrete frost resistance was significantly higher than the base concrete, concrete fiber, polypropylene fiber reinforced concrete antifreeze of the best, followed by alkaliresistant glass fiber reinforced concrete, steel fiber reinforced concrete for the worst.A base of concrete, steel fiber reinforced concrete, alkaliresistant glass fiber reinforced concrete, polypropylene fiber reinforced concrete comparison of the anticarbonation tests and found that anticarbide fiberreinforced concrete base was significantly higher than that of concrete, concrete fiber, polypropylene fiber reinforced concrete carbonation of the best, followed by alkaliresistant glass fiber reinforced concrete, steel fiber reinforced concrete for the worst.Comprehensive comparative analysis of the base concrete, steel fiber reinforced concrete, alkaliresistant glass fiber reinforced concrete, polypropylene fiber reinforced concrete durability, fiber reinforced concrete on the mechanism of the enhancement.
