Abstract
The aim was to produce data to find a suited test method and sand parameters for determination
of the void ratio parameter for crushed sand to be used in the "particle-matrix-model – PMM.
PMM considers workability from the volumetric ratio between the viscous matrix phase and the
solid particle phase. The results confirm that the voids ratio varies between different filling
procedures and compaction levels. Four different sands were tested, representing various grain
shape. The results show that the traditional concept of “open and “dense” grain size distributions
correspond to high and low voids ratio, respectively, and that increasing angularity of the grains
contributes to increased voids ratio.
