Testing and Certification of fiber products for concrete

    Fiber reinforced concrete is a new type of concrete composite material with the fastest development and the most extensive application in recent years. Adding a small amount of fiber into the concrete matrix can make the physical properties of concrete change, so as to greatly improve the toughness, compressive resistance and impact resistance of concrete, so that concrete from the traditional low tensile brittle material to high strength and high toughness material. Therefore, it is widely used in tunnel, road surface, bridge, civil construction, water conservancy, mining, metallurgy, port, airport and other concrete structure engineering.

 

    Steel fiber is a high-risk product in construction engineering, and its quality and material directly affect the safety and long-term durability of buildings. Therefore, customers pay great attention to whether such products have passed the European CE certification when purchasing, because the strict factory review and various tests carried out on the products during the CE certification process ensure that the various processes and performance of their products are within the scope of European standards, so that not only ensure the safe use of products in the construction process, It also ensures that the product will not produce harmful substances after delivery.

 

Fiber for concrete can be divided into two categories: steel fiber and polymer fiber

 

Concrete fiber CE certification cited standards are:
