Cement Bulk Density
I need to convert silo volume to weight of the portland cement stored there. The density rule of thumb I have used in the past is in question and I cannot find any definitive reference.
What is the bulk desity pounds/cubic^3 or kg/m^3:
After conveying pneumatically?
After it has time to settle in the silo?
I need general guidlines for extimating purposes and am aware of the many variables that affect this value.
I would appreciate anyone with portland cement experiance to comment on this question.
