SIEVING OF AGGREGATES, SOME OBSERVATIONS

SIKTNING AV STENAGGREGAT, NAAGRA IAKTTAGELSER

The aim of this report is to highlight some aspects which arose during the preparation of the test standard for the sieve analysis of aggregates. One aspect was the reason for an observed increase in fines content at prolonged sieving. Such an increase may be the consequence of particle wear. Another was the influence of the amount of material in the sieve. Both questions are important in conjunction with maximum input and sieving time. The study gave strong indications that wear is of minor importance at least with materials of reasonable strength, and that the input limitation is essentially set by the volume capacity of the sieves, since the vibrator used (Pascall Inclyno) showed unexpectedly high sieving capacity. The study comprised granite as well as limestone, gravel, crushed material and spherical glass beads. (Author/TRRL)
