The unit weight of different building materials is essential to know to analyze the structure. Unit weight of most commonly used building materials is given below for the handy reference.
|Building Material||Unit Weight in kN per Cubic meter otherwise specified|
|Lime Mortar||15.70 to 18|
|Bricks||16 to 19|
|Reinforced Cement Concrete (RCC)||25|
|Plain Cement Concrete||24|
|Coarse aggregates||16 to 19|
|AAC (Autoclave aerated concrete)||5.5 to 6.5|
|Sand (dry)||15.10 to 15.70|
|Sand (wet)||17.25 to 19.60|
|Granite (stone)||25.90 to 27.45|
Though this list is not exclusive, it is helpful for the site engineers, architects and as well as diploma or degree engineering students.
One more note to this is that there is Indian Standard IS:875-1987 (Part – 1) that has a much detailed explanation of the unit weight of building materials. You can download IS:875-1987 (Part – 1) here.
