Abstract (en)

An apparatus for adding to a concrete mixture a desired quantity of fibre cut e.g. of plastic. The apparatus comprises a concrete mixer (5), at least one hopper (6a-d) for storing a supply (15) of fibre cut, a dosing mechanism (11, 14) for taking out for each mixing cycle the desired quantity of fibre cut from the said supply (15), a conveyor (8; 27) for conveying the fibre cut to the concrete mixer (5), and a smoothing device (19a-b; 29) for distributing in the course thereof the quantity of fibre cut taken out evenly during the dry mixing. By the invention it is possible to obtain a far more even and more uniform distribution of plastic fibres in concrete than has been known before, whereby the material improving properties of the plastic fibres are optimally exploited. <IMAGE>
