What is the difference between packing density and bulk density in building materials?

What is the difference between packing density and bulk density in building materials?

Answer:

Filling density: for solid blocks; such as concrete, brick, block
Bulk density: for the scattered material; such as cement, sand
in the material volume Porosity: Porosity is the percentage of the volume of voids between the particles in the volume of the bulk material in a container Porosity (Hollow Rate): Percentage of the ratio of the sum of the volume of holes and slots of hollow bricks and hollow blocks to the volume calculated from outside dimensions the higher the relationship density, the greater the apparent density, the smaller the porosity The greater the porosity, the apparent density is not necessarily small, the density is not necessarily small The greater the porosity, the greater the bulk density The greater the water absorption
