Method for producing in a continuous installation a compacted rolled concrete composition reinforced with metal fibres, and continuous installation therefor

摘要

The invention concerns a method for producing in a continuous installation a compacted rolled concrete composition reinforced with metal fibres, which consists in feeding a vibrating metering means with pre-sized metal fibre plates to be delivered on a conveyor in a proportion ranging between 25 and 60 kg of fibres per m<3> of dry fibre-free concrete constituents, and in supplying a hydraulic binder in a proportion ranging between 180 and 400 kg/m<3> of dry fibre-free concrete constituents, the proportion of mixing water being determined such that the mixer delivers continuously a composition having a water content between 90 and 150 litres of water per m<3> of dry fibre-free concrete constituents.
