鋼纖維混凝土小知識
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.
纖維增強混凝土(FRC) 是混合了纖維材料以提高混凝土耐久性和結構完整性的混凝土。FRC 具有小而短且隱蔽的纖維,這些纖維取向隨機但均勻分布在整個混凝土中。纖維可以是圓形的,也可以是扁平的,通常占混凝土混合物總體積的百分之一到百分之三。鋼筋混凝土中常用的纖維包括鋼、玻璃、合成纖維和天然纖維。
Why fibres are used? 為什么要使用纖維?
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,混凝土缺乏抗拉強度,容易開裂。但纖維增強混凝土可以提高混凝土結構的抗拉強度并控制通常由塑性收縮和干燥收縮引起的開裂。混凝土中的纖維還可以降低混凝土的滲透性,從而限制滲出的水量,進一步減少養護過程中的收縮開裂。
The necessity of Fiber Reinforced Concrete纖維增強混凝土的必要性
1- It increases the tensile strength of the concrete.
1-它增加了混凝土的抗拉強度。
2- It reduces the air voids and water voids the inherent porosity of gel.
2-它減少了空氣空隙,水空隙凝膠固有的孔隙率。
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-石墨和玻璃等纖維具有出色的抗蠕變性,而大多數樹脂則不然。因此,纖維的取向和體積對鋼筋/鋼筋的蠕變性能有顯著影響。
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-鋼筋混凝土本身是一種復合材料,其中鋼筋充當增強纖維,混凝土作為基體。因此,兩種材料在熱應力下的行為必須相似,以便將混凝土和鋼筋的差異變形降至最低。
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- 人們已經認識到,在混凝土中添加小的、緊密間隔的、均勻分散的纖維將起到防裂劑的作用,并將大大改善其靜態和動態性能。
