钢纤维混凝土小知识
Fiber-reinforced concrete (FRC) is concrete that has fibrous materials mixed in to increase the concrete’s durability and structural integrity. FRC has small, short, and discreet fibers that are randomly oriented yet uniformly distributed throughout the concrete. The fibers can be circular or flat and often make up one to three percent of the concrete mix’s total volume. Common fibers used in reinforced concrete include steel, glass, synthetic, and natural fibers.
纤维增强混凝土（FRC） 是混合了纤维材料以提高混凝土耐久性和结构完整性的混凝土。FRC 具有小而短且隐蔽的纤维，这些纤维取向随机但均匀分布在整个混凝土中。纤维可以是圆形的，也可以是扁平的，通常占混凝土混合物总体积的百分之一到百分之三。钢筋混凝土中常用的纤维包括钢、玻璃、合成纤维和天然纤维。
Why fibres are used? 为什么要使用纤维？
On its own, concrete lacks tensile strength and is prone to cracking. But fiber-reinforced concrete can improve tensile strength and control cracking in concrete structures that are often caused by plastic shrinkage and drying shrinkage. Fibers in concrete can also reduce the permeability of concrete, which limits the amount of water that bleeds out, further reducing shrinkage cracking during curing.
就其本身而言，混凝土缺乏抗拉强度，容易开裂。但纤维增强混凝土可以提高混凝土结构的抗拉强度并控制通常由塑性收缩和干燥收缩引起的开裂。混凝土中的纤维还可以降低混凝土的渗透性，从而限制渗出的水量，进一步减少养护过程中的收缩开裂。
The necessity of Fiber Reinforced Concrete纤维增强混凝土的必要性
1- It increases the tensile strength of the concrete.
1-它增加了混凝土的抗拉强度。
2- It reduces the air voids and water voids the inherent porosity of gel.
2-它减少了空气空隙，水空隙凝胶固有的孔隙率。
3- It increases the durability of the concrete.
3-它增加了混凝土的耐久性。
4- Fibers such as graphite and glass have excellent resistance to creep, while the same is not true for most resins. Therefore, the orientation and volume of fibers have a significant influence on the creep performance of rebars/tendons.
4-石墨和玻璃等纤维具有出色的抗蠕变性，而大多数树脂则不然。因此，纤维的取向和体积对钢筋/钢筋的蠕变性能有显著影响。
5- Reinforced concrete itself is a composite material, where the reinforcement acts as the strengthening fiber and the concrete as the matrix. It is therefore imperative that the behavior under thermal stresses for the two materials be similar so that the differential deformations of concrete and the reinforcement are minimized.
5-钢筋混凝土本身是一种复合材料，其中钢筋充当增强纤维，混凝土作为基体。因此，两种材料在热应力下的行为必须相似，以便将混凝土和钢筋的差异变形降至最低。
6- It has been recognized that the addition of small, closely spaced, and uniformly dispersed fibers to concrete would act as a crack arrester and would substantially improve its static and dynamic properties.
6- 人们已经认识到，在混凝土中添加小的、紧密间隔的、均匀分散的纤维将起到防裂剂的作用，并将大大改善其静态和动态性能。
Types of Fibers 纤维的种类
1- Steel fibers 1-钢纤维
2- Glass fibers 2-玻璃纤维
3- Carbon Fibers 3-碳纤维
4- Cellulose Fibers 4-纤维素纤维
5- Synthetic Fibers 5-合成纤维
6- Natural Fibers 6-天然纤维

2-Ideal aspect ratio (i.e. the relationship between Fiber diameter and length) which makes them excellent for early-age performance.
2-理想的纵横比（即纤维直径和长度之间的关系），这使得它们在早期表现方面表现出色。
3-Easily placed, Cast, Sprayed and less labor-intensive than placing rebar.
