| 摘要 |
<p>The present invention relates to an ultra-high performance concrete including a hybrid fiber, and more particularly, to an ultra-high performance fiber reinforced concrete composition using a hybrid steel fiber, in which a long fiber having a torsional cross-section is admixed to improve the mechanical properties of the concrete, and to control macro cracks due to the shape of the torsional cross-section, and in which a short fiber having a circular cross-section is admixed to control micro cracks, thereby improving the overall mechanical properties of the high performance concrete, and a method for manufacturing same.</p> |
