Typically the fibers are added at the batch plant, just after all concrete aggregates are being mixed. The spacing mechanism requires a large number of fibres well distributed within the concrete matrix to arrest any existing micro-crack that could potentially expand and create a sound crack. The first may be described as Design on the basis of material properties. 5- Reinforced concrete itself is a composite material, where the reinforcement acts as the strengthening fibre and the concrete as the matrix. The fibres can be circular or flat, and often makeup one to three per cent of the concrete mix’s total volume. 0000004449 00000 n SikaFiber® Novocon®. Adding high performance steel fibres, concrete will behave like a composite material with an important gain in structural ductility and shrinkage control. When added to the concrete mix, the bundles are spread throughout the concrete. Advantages of Steel Fibers in Concrete .
