What is bulk density of cement, aggregate, sand? Quora

For sand bulk density is 14501650 kg/m^3 and the bulk density of aggregate depends upon their packing, the particles shape and size, the grading and the moisture coarse aggregate a higher bulk density is an indication of fewer voids to be filled by sand and cement.

RELATIVE DENSITY TEST IIT Kanpur

Relative density is an arbitrary character of sandy deposit. In real sense, relative density expresses the ratio of actual decrease in volume of voids in a sandy soil to the maximum possible decrease in the volume of voids how far the sand under investigation can be capable to the further densification beyond its natural state. Determination of relative density is helpful in compaction of ...

Crusher Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated. Crushing is the process of ...
