The Mechanical Behavior of Reactive Powder Concrete with Different Steel Fiber Volume Contents

Abstract:

Through uniaxial compression test, tensile splitting test and bending test, we have researched the three kinds basic mechanical behaviors of Reactive Powder Concrete (RPC for short) with different steel fiber volume contents at 0%, 1%, 2% and 4% respectively. According to the result, the tensile splitting strength is a linear increase nearly with the increase of steel fiber volume content; and the bending strength is also increase with the increase of steel fiber volume content, When steel fiber volume content increases from 1% to 2%, the growing rate of bending strength reaches to maximum. When steel fiber volume content is within 4%, the compressive strength increases with the increase of steel fiber volume content. The compressive strength of plain RPC can reach to 135MPa, and the RPC with 4% steel fiber volume content is about 220MPa. This information can tell us that the addition of steel fiber in RPC can get an great increase of strength and toughness.
