초록
This study was performed to evaluate the effective analysis of flexural performance for polypropylene fiber (PF) reinforced EVA concrete that can beused in marine bridge, tunnel and agricultural structures under flexural load. The control design was applied in ready mixed concrete using 10 % fly ashof total binder weight used in batch plant. On the basis of the control mix design, there was designed mix types that contained PF ranged from 0 % to 0.5% by volume ratio into two mix types of using 0 % and 5.0 % EVA contents of total binder weight. Before evaluating the flexural performance, we testedcompressive strength and flexural strength to evaluate whether polypropylene fiber reinforced concrete could be used or not in site. The method offlexural performance evaluation was applied by ASTM C 1609. These results showed the maximum compressive strength and flexural strength wasmeasured at each E5P1 and E5P2. Concrete reinforced with PF exhibited deflection-softening behavior. In the concrete reinforced with 0.4 % PFcontents and containing 5.0 % EVA, the flexural performance was the best.
