    • The present invention relates to a circular steel fiber used for shotcrete, which is formed in the shape of a ring with both ends separated from each other and inserted into shortcrete. The circular steel fiber of the present invention reduces a loss rate of steel fiber compared to a straight steel fiber when pouring shortcrete, improves the flexural toughness of shortcrete by preventing pull-out after pouring concrete, and reduces manufacturing costs because the used amount is optimized due to the increased rebound rate and flexural toughness.
    • 本发明涉及一种用于喷浆混凝土的圆钢纤维,其形成为两端彼此分离并插入短混凝土的环形。 本发明的圆钢纤维在浇注混凝土时与直钢纤维相比降低了钢纤维的损失率,通过防止浇筑混凝土之后的拉出,提高了短混凝土的弯曲韧性,并且由于使用量被优化而降低了制造成本 由于回弹率和弯曲韧性的提高。
