钢纤维是世界上广泛应用的一种混凝土加强材料，外观：光滑、明亮，与普通的混凝土相比，加入钢纤维的混凝土其抗压强度、拉伸强度、抗弯强度、冲击强度、韧性、磨损、抗裂、冲击韧性等性能均得到较大提高，并可以适当减少原结构配筋。钢纤维主要作用是阻碍混凝土内部微裂缝的扩展和阻滞宏观裂缝的发生和发展。

       钢纤维常见的型号有：446#  430# 304#  310#。除446#之外，凡是以4字开头的钢纤维，都是不锈钢纤维，因为它们有一个共同的特点，就是含有铬(Cr)。 4字头钢纤维都含有耐蚀性贵金属：铬（Cr），因为Cr的强耐蚀性，所以广泛被用于冶金行业，耐材行业，化工行业，被钢厂，冶金厂和化工厂等所用，比如钢厂的钢水槽，电极，冶金厂的炉壁，炉门，炉顶封盖等。

Steel fiber is a kind of concrete reinforced material widely used in the world. Appearance: smooth and bright. Compared with ordinary concrete, adding steel fiber concrete compressive strength, tensile strength, bending strength, impact strength, toughness, wear, crack resistance, impact toughness and other properties were improved greatly, and can decrease the original structure reinforcement. The main effect of steel fiber is to prevent the expansion and development of micro-cracks in concrete.

The most common types of steel fiber are: 446 # 430 # 304 # 310 #. In addition to 446 #, all steel fibers that start with four words are stainless steel, because they have a common feature, which is chromium (Cr). 4 "contain the corrosion resistance of steel fiber for precious metals: chromium (Cr), because of strong corrosion resistance of Cr, so widely used in metallurgical industry, refractory material industry, chemical industry, widely steel mills, used by metallurgical plant and chemical plant. Steel sinks, electrodes, furnace walls, furnace doors, roof caps, etc.

       １、收缩性能明显改善；裂缝的控制；钢纤维对混凝土结构的加固是三维全截面的、整体的、且各向同性的，在混凝土中无论哪个部位，钢纤维都能起到加固作用，能充分控制地坪裂缝的宽度。  

      ２、具有较高的抗拉、抗弯、抗剪和抗扭强度；由于钢纤维本身具有很高的抗拉强度（大于100MPa），及两端弯钩保证钢纤维与混凝土有效锚固，在混凝土中有效传送与分配应力，使裂缝化解为散置的微细裂缝。用钢纤维加固的地坪，其裂缝宽度将远小于钢筋混凝土地坪裂缝宽度。       

       ３、具有 的抗冲击性能；由于钢纤维提高了混凝土板的韧度和延性，将混凝土材料性质由原来的脆性变为柔性，因而在控制混凝土变形产生的裂缝方面，钢纤维的增 果好。

       ４、耐久性能显著提高，混凝土耐久性有效改善。可提高其抗冲击性，耐磨性及疲劳强度和韧性。减少冲击和摩擦所产生的表面损失。

       ５、抗疲劳性能显著提高；对大幅度温度变化具有较佳抗力：混凝土在温度骤然上升和下降的情况下会产生剥落现象，钢纤维和混凝土具有很强的握裹力，故可以阻止此现象的发生。

Significant improvement in contraction performance; Control of the cracks; Steel fiber on concrete structure reinforcement is the three dimensional whole cross section, the overall and isotropic, regardless of which part in the concrete, steel fiber can reinforce effect, can control the width of the floor cracks.

High tensile, anti-bending, anti-shear and torsion strength; Due to the tensile strength of steel fiber itself has very high (more than 100 mpa), and hook on both ends ensure effective anchorage steel fiber and concrete, effective transmission and distribution of stress in the concrete, dissolve for scattered micro cracks. The width of the cracks will be much smaller than the cracks in the concrete floor.

Having excellent impact resistance; Because of the steel fiber can improve the toughness and ductility of concrete plate, will be from the original concrete material brittleness is a flexible, so in terms of controlling the deformation of concrete cracking, steel fiber enhancement effect is good.

The durable performance improved significantly, and the durability of concrete was improved. It can improve its impact resistance, abrasion resistance and fatigue strength and toughness. Reduce the surface damage caused by shock and friction.

Significant improvement in resistance to fatigue; Have better resistance to temperature changes greatly, the concrete in the case of temperature rising and falling sharply produces peeling phenomenon, has a strong grip of fiber and concrete, so it can prevent the occurrence of this phenomenon.

According to the surface coating, the coating is not coated, coated with epoxy resin, galvanized etc. There is a large amount of uncoated steel fiber in the industry.

According to the construction process, the use of spray and pouring.

7, according to the size of the diameter: plain steel fiber (d > 0.08 mm); Ultra fine steel fibre (d less than 0.08 mm); Ultrafine steel fibers are used mainly to enhance plastic and asbestos friction materials.
