THE TECHNOLOGY OF STEEL FIBRE REINFORCED CONCRETE FOR PRACTICAL APPLICATIONS. SOME PRACTICAL APPLICATIONS OF STEEL FIBRE REINFORCED CONCRETE

Fibre-reinforced concrete is concrete containing round or flat steel fibres with dimensions of less than a millimetre, from 10 to 80 mm long and either straight or sinusoidal in shape. In principle, fibres are randomly distributed to give concrete with isotropic resistance but, sometimes, the fibres are placed in a specific direction to strengthen the concrete's resistance in this particular direction. The article describes the technology of preparing the concrete and gives its properties. Diagrams show the increased bending and compressive strength. The fibres prevent cracking or, at least, slow up the spread of cracks. Resistance up to temperatures of 1000 deg F and thermal conductivity are improved. Lastly, its energy absorption capacity means it is highly resistant to impact and the connected disintegration effect. The second article describes supporting slabs, pipes, floors and tunnel linings made with this concrete and their behavior.
