N2 - The segregation of commercial dry mineral-based construction products and a mixture resembling these has been investigated in silos of different scale, and the results are presented in two parts. This work encompasses the first part, where the segregation of four different construction products at discharge from a 70m3 silo is followed at a production plant in Finland. In addition, the segregation of two other construction products at discharge from two different 20m3 silos is determined. Finally, the segregation of a three-component mixture resembling real construction products is investigated in a small (0.5m3) silo. The results show that a similar segregation pattern, that is, increase of fine material at the end of discharge, is obtained regardless of scale. Although the degree of segregation depends on silo size and material properties, the results of this work show that segregation of commercial construction products in large scale can very well be investigated with idealized mixtures in small scale with the advantage of more controlled experimental conditions and ease of generating quantitative data at reduced cost.
