EN14889-1鋼纖維CE認證法規及體系

鋼纖維CE認證根據歐盟CPR建築產品法規，根據EN 14889-1協調標準採用體系1或體系3進行測試認證。體系1需要歐盟公告號認證機構（歐盟NB公告機構）對工廠進行持續監督並對產品測試評估。體系3需要歐盟公告號認證機構對工廠產品進行測試。
鋼纖維CE認證體系3及體系1的認證費用，認證要求完全不同http://www.hksmartps.com。具體請諮詢南京睿督公司。

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佈在整個混凝土中。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?  為什麼要使用纖維？
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並控制通常由塑性收縮和乾燥收縮引起的開裂。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複合材料，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，並將大大改善其靜態和動態性能。

Types of Fibers 纖維的種類

1- Steel fibers 1-鋼纖維
2- Glass fibers 2-玻璃纖維
3- Carbon Fibers 3-碳纖維
4- Cellulose Fibers 4-纖維素纖維
5- Synthetic Fibers 5-合成纖維
6- Natural Fibers 6-天然纖維

Advantages Of Fibre Reinforced Concrete
纖維增強混凝土的優點

1-High modulus of elasticity for effective long-term reinforcement, even in the hardened concrete. Does not rust nor corrode and requires no minimum cover.
1-高彈性模量，即使在硬化混凝土中也能實現有效的長期加固。不會生銹或腐蝕，並且不需要最低限度的覆蓋。

2-Ideal aspect ratio (i.e. the relationship between Fiber diameter and length) which makes them excellent for early-age performance.
2-理想的縱橫比（即纖維直徑和長度之間的關係），這使得它們在早期表現方面表現出色。 

3-Easily placed, Cast, Sprayed and less labor-intensive than placing rebar.
3-易於放置，鑄造，噴塗，並且比放置鋼筋更省力。

4-Greater retained toughness in conventional concrete mixes.
4-在傳統混凝土混合物中保留韌性更高。

5-Higher flexural strength, depending on the addition rate.
5-更高的抗彎強度，取決於添加率。

6-Can be made into thin sheets or irregular shapes.
6-可製成薄片或不規則形狀。

7-FRC possesses enough plasticity to go under large deformation once the peak load has been reached.
7-FRC具有足夠的塑性，一旦達到峰值載荷，就會發生較大的變形。8- Increased durability and high flexural rigidity.8-增加耐用性和高彎曲剛度。

9-Reduced permeability, bleeding, and formation of microcracks.
9-降低滲透性、滲色和微裂紋的形成。

10-Minimum weathering effect.

11-Reduces deflection. 
11-減少偏轉。

12-Minimum corrosion.
12-最小的腐蝕。
