Experimental Study on the Flexural Tensile Properties of Fiber Reinforced Light-Weight Aggregate Concrete

Abstract:

In order to investigate the effect of fiber reinforced light-weight aggregate concrete on flexural tension properties, five groups of steel fiber reinforced light-weight aggregate concrete (SFLWAC) specimens with different steel fiber volumes including 0.5%,1.0%,1.5%,2.0%,2.5% and another five groups of plastics-steel fiber reinforced light-weight aggregate concrete (PSFLWAC) specimens with different plastics-steel fiber volumes including 0.5%,0.7%,0.9%,1.1%,1.3% were tested. The test results show that fiber can greatly improve ductility, and there are good interfacial bonding properties between fiber and light-weight aggregate concrete. The test results also show that it is not obvious to the upgrade of the flexural strength of light-weight aggregate concrete of LC30 with plastics-steel fiber. But the addition of steel fiber can gradually improve the breaking strength owing to the increase of steel fiber volumes.
