  • Method of reinforcing concrete with fibres
    Patent number: 4062913
    Abstract: The invention relates to the reinforcement of material with fibres, whereby the fibres are orientated by means of electrical fields. In this way, the fibres can also be concentrated on places which are especially subjected to stress so that a considerably greater strength increase is obtained from a smaller amount of reinforcement fibres than used in conventional methods.
