![]() ![]() There are several materials used in building construction work. It is described asĪbsolute Specific Gravity = ( Weight of oven-dried aggregate at 100°c for 24 hours) / ( Weight of water’s volume equal to that of aggregate’s solids excluding pores)ĭensity of Building Materials As Per IS 875 Part-1ġ KN/m 3 = 101.9716 kg/m3 say = 100 kg/m 3 (round off)ġ Kg/m 3 = 0.0624 lb/ft 3 Construction Materials The specific gravity of aggregate excluding all pores is referred to as the absolute specific gravity. Relative Density or Specific Gravity of AggregateĪggregate Contains both permeable and impermeable pores. The approximate value of bulk density for aggregate usually used for normal-weight concrete varies between 1200-1750 Kg/m 3or 75 to 110 lb/ft 3.In the above definition, the volume contains both aggregates along with voids between aggregate particles.Bulk density is equal to mass if the volume is unit.It also indicates the aggregate grading and shape.īulk Density = Weight of aggregate / Container of unit volume It helps to convert quantities by weight to by volume. It is the weight of aggregate needed to fill a unit volume of the container. For structural concrete common materials like gravel and crushed stone are used.Īlso, Read – What is M Sand? Properties, advantages, Disadvantages. and 63 mm for plain cement concrete work.įor reinforced cement concrete work usually, 20 mm size aggregate is preferred. The maximum size maybe 20 cm for mass concrete, such as in dams etc. ![]()
