WHAT IS Bulk DENSITY OF MATERIAL? Explanation of phycial material

Bulk Density (ρb)





mass per unit volume of material in its natural state (with pores and voids)

                                                                                                                            
    ρb = M / V

Where M = Mass and V= Volume of specimen in its natural state

       For most materials, bulk density is less than density

       But for liquids and materials like glass and dense stone materials, these 

parameters are practically the same.

       Properties like strength and heat conductivity are greatly affected by their bulk density.
















Bulk densities of some of the building
materials are as follows

Material
Bulk density (kg/m3)
Brick
1600–1800
Granite
2500–2700
Sand
1450–1650
Pine wood
500–600
Steel
7850
























WHAT IS DENSITY OF MATERIAL? Explanation of phycial material

  1. Density (ρ)


Mass per unit volume of homogeneous 

material (without counting voids)
.  ρ = M / V

          Where M = Mass and V= Volume

Density of some building materials is as 


Brick
2.5–2.8
2500-2800
Granite
2.6–2.9
2600-2900
Portland cement
2.9–3.1
2900-3100
Wood
1.5–1.6
1500-1600
Steel
7.8–7.9
7800-7900
