  • Advantages of steel fibre reinforced concrete over traditional




    Rejuva floors concrete was the solution given to the deficiencies of concrete alone. Despite the robust appearance of this material, it could be considered quite fragile when it comes to the truth.

    Although it can withstand very high loads, when these are overcome, instead of deforming, it breaks directly. This indicates to us, therefore, that its resistance to flex traction is very weak.

    For this reason, an electro-welded mesh has always been added to the concrete, thus giving rise to what is known as reinforced concrete. This was the best way until now to overcome the low flexibility of this material.

    However, there is now a much more effective way: adding steel fibres to it. When such fibres are implemented, it is no longer necessary to add the reinforcement that has traditionally been included.

    They achieve a much better effect and are also a more economical alternative. So, to help you understand why it is ideal to opt for concrete slabs reinforced with steel fibres, in this article we are going to talk about the advantages they offer.

    The Three Semi-Finished Product Groups

    The three main finished steel product groups are tube, flat products and long products. These finished products are produced from semi-finished steel products which are usually made by continuous casting of liquid steel. These so-called semis comprise,
    • billet: typically a square some 6 or 12 meters in length with cross-sectional area of 100 - 120 mm square to a maximum of 180 - 200 mm square - used for long products and seamless tube
    • slab: usually up to 12 meters in length and conventionally from ~150 mm up to ~400 mm thick - used for flat products (and subsequently, welded tube)
    • bloom: usually above 180 or 200mm square to around 300 - 360 mm square (to a maximum of ~400 mm square) - used for large section and long products.
    Turning to the different finished product groups,
    • billet is normally hot-rolled into light long products. These products generally comprise bar - which can be round, square, angled etc. This light long category often includes merchant bar products (rounds, squares, hexagons, rectangles, flats etc used mainly as support structures for building, construction, machinery) as well as reinforcing bar (typically 8 - 18 mm in diameter, and used for concrete reinforcement). Light long products can also include wire rod, which is generally under 13.5 mm in diameter, and is formed in coils rather than in lengths. Steel wire, steel mesh, nails and other fasteners are typically made from wire rod.
    • slab is normally hot rolled into plate or into hot rolled coil. Beyond this step, there is cold rolling, which usually takes hot rolled steel coil and further reduces the gauge to produce cold-rolled coil. Cold-rolled steel can be used as such (e.g. in machine components), but is often coated to produce zinc coated sheet or tin plate. Zinc coated sheet is often processed further still - to make so-called organic coated sheet - where a plastic coating further adds to the anti-corrosive properties of the steel.
    • bloom is typically rolled in a blooming mill, to produce large sections or very big bar shapes.
    • welded tube in turn is usually made by bending of hot rolled coil or sheet (made from slab); although plate or cold-rolled steel can also be used for welded tube making depending on the desired wall thickness.
    • seamless tube is usually made by billet piercing.

      I need repair and renovation for my home and I have discovered concrete contractors boston to my cousin. I'll will try to call them later to discuss about the project.
