Experimental Study on Flexural Behavior of Ductile High Performance Concrete

Abstract:

Considering the effects of fibers content, water-binder ratio, sand-binder ratio and fly-ash content, 16 groups of ductile high performance concrete specimens were designed by the method of orthogonal test, whose flexural performance were tested by the four-point bending test. By analysis of ultimate flexural strength, equivalent flexural strength and toughness indexes of 16 groups specimens, the results indicated that the load-deflection curves of other 12 groups specimens showing the typical strain hardening features except for the four groups, in which the fiber content equals to 0.5%. The flexural behaviors were affected by the fiber content most. The more the fiber, the higher the flexural toughness. The effect of fly ash on the flexural performance was very little, the more the fly ash, the higher the flexural toughness.
