PROCESS FOR RECYCLING PLASTIC SCRAP, MIXING-IN MACHINE USED FOR THIS PURPOSE, FIBRES, BUILDING MATERIALS AND FIBRE-REINFORCED CONCRETE

摘要

The invention relates to a process for recycling plastic scrap, where the plastic scrap is cut to form fibres and mixed into concrete. Preferably, the fibres are provided with a cross-sectional shape which changes over their length and are roughened on the surface. The invention further relates to a mixing-in machine for mixing in the fibres, which is characterized in that choppers 7, 8, 9 for cutting to the desired fibre length, plus a compressed air stream for transporting the fibres and a mixing chamber 19 for depositing the fibres on or in the concrete premix fed in are provided.
