WEAR RESISTANCE OF FIBER REINFORCED CONCRETE

The use of studded tyres as well as the price explosion of asphalt materials has made concrete more suitable as an economic material for highway construction. Fibres as reinforcing material in concrete were expected to improve the wear resistance but field tests have, until now, not confirmed this. The research program reported was limited and firm conclusions cannot be drawn. However, interesting mechanisms were found which partly explain the unexpected results in the field tests. The results indicate that the krenit polypropylene fibres alone or in combination with steel fibres with hooked ends can improve the wear resistance of concrete significantly. Steel fibres alone can improve the wear resistance provided that they are not too stiff and that there are enough of them. Glass fibres will reduce the wear resistance. When using fibres in concrete, the concrete should be relatively rich and the coarse aggregate should, normally, have a maximum diameter not over 8-12 mm. (TRRL)
