                用于制造鋼纖維混凝土,任何方法生產的鋼纖維都能起到強化混凝土的作用。纖維的增強效果主要取決于基體強度(fm),纖維的長徑比(鋼纖維長度l與直徑d的比值,即I/d),纖維的體積率(鋼纖維混凝土中鋼纖維所占體積百分數),纖維與基體間的粘結強度,以及纖維在基體中的分布和取向(η)的影響。當鋼纖維混凝土破壞時,大都是纖維被拔出而不是被拉斷,因此改善纖維與基體間的粘結強度是改善纖維增強效果的主要控制因素之一。加入鋼纖維的混凝土其抗壓強度、拉伸強度、抗彎強度、沖擊強度、韌性、沖擊韌性等性能均得到較大提高。 Steel fiber reinforced concrete and steel fiber produced by any method can strengthen the concrete. The reinforcing effect of fiber depends mainly on the strength of the matrix (FM), the ratio of the length to diameter of the fiber (the ratio of the length of steel fiber to the diameter of L and the diameter of D, that is, I/d), the volume rate of the fiber (the percentage of the steel fiber in the steel fiber concrete), the bond strength between the fiber and the matrix, and the distribution and orientation of the fiber in the matrix (ETA). Influence。 When the steel fiber reinforced concrete is destroyed, most of the fiber is pulled out rather than broken. Therefore, the improvement of the bond strength between the fiber and the matrix is one of the main control factors to improve the fiber reinforcement effect. The compressive strength, tensile strength, flexural strength, impact strength, toughness and impact toughness of the steel fiber reinforced concrete are greatly improved.
