| 钢纤维按材质分，有普通碳钢钢纤维和不锈钢钢纤维，其中以普通钢钢纤维用量居多;按外形分有长直形、压痕形、波浪形、弯钩形、大头形、扭曲形;按截面形状分有圆形、矩形、月牙形及不规则形;按生产工艺分有切断型、剪切型、铣削型及熔抽型;按施工用途分有浇筑用钢纤维和喷射用钢纤维。为满足钢纤维的增强效果与施工性能，通常采用钢纤维长度为15～60mm，直径或等效直径为0.3～1.2mm，长径比为30～100，纤维的体积掺量为0.5%～2%。 Steel fibers are classified according to material quality, including ordinary carbon steel fibers and stainless steel fibers, in which the amount of common steel fibers is the majority; according to shape, they can be divided into straight, indentation, wave, hook, large head and twist; according to section shape, they can be divided into circular, rectangular, crescent and irregular shapes; according to production technology, they can be divided into cutting, shearing, milling and melting-pulling types; according to construction purpose, they can be divided into three types. Steel fibers for casting and spraying. In order to satisfy the reinforcement effect and construction performance of steel fibers, the length of steel fibers is 15-60 mm, the diameter or equivalent diameter is 0.3-1.2 mm, the ratio of length to diameter is 30-100, and the volume fraction of steel fibers is 0.5-2%. 钢纤维的主要性能：钢纤维的主要性能包括抗拉强度与黏结强度。试验表明，由于普通钢纤维混凝土主要是因钢纤维拔出而破坏，并不是因钢纤维拉断而破坏，因此钢纤维的抗拉强度一般能满足使用要求，而其与混凝土基体界面的黏结强度是影响钢纤维混凝土性能的主要因素。黏结强度除与基体的性能有关外，就钢纤维本身而言，与钢纤维的外形和截面形状有关。 Main properties of steel fibers: The main properties of steel fibers include tensile strength and bond strength. The test results show that the tensile strength of steel fiber can generally meet the www.tangangfengtou.cnwww.tubuji.com.cnwww.tiemianji.cnwww.diandongmens.cn www.yazhujian.com.cnwww.caoxingtuogun.cnrequirements of service, and the bond strength between steel fiber and concrete matrix is the main factor affecting the performance of steel fiber reinforced concrete. In addition to the properties of the matrix, the bond strength is related to the shape and cross-section of the steel fiber itself. |
