Lightweight aggregate is the generic name of a group of aggregates having a relative density lower than normal density aggregates (natural sand gravel and crushed stone) sometimes and is referred to as low density aggregate Structural lightweight aggregate-Structural aggregate meeting the Specific Gravity Of General Materials Table Gravel 110 1762 Grinding Compound 99 1586 Ground Bone
EVALUATION OF NEW TEST PROCEDURES FOR DETERMINING BULK SPECIFIC GRAVITY OF FINE AGGREGATE BY AUTOMATED METHODS Two automated methods were evaluated for determining the dry bulk specific gravity (Gsb) of fine aggregates Thermolyne SSDetect and InstroTek CoreLok Each proposed method was evaluated against the standard method described in AASHTO
Aggregates may be broadly classi fied as natural or artificial both with respect to source and to method of preparation Natural sands and gravels are the product of weathering and the action of wind or water while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone Crushing
As specific gravity is just a comparison it can be applied across any units The density of pure water is also 62 4 lbs/cu ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0 73 then we can calculate that its density is 0 73 x 62 4 = 45 552 lbs/cu ft Note kg/cu m divided by 16 02 = lbs/cu ft

Crushed And Uncrushed Aggregates We are a large-scale manufacturer specializing in producing various mining machines including different types of sand and gravel equipment milling equipment mineral processing equipment and building materials equipment And they are mainly used to crush coarse minerals like gold and copper ore metals like steel and iron glass coal asphalt gravel
Knowing the specific gravity of aggregates is also critical to the construction of water filtration systems slope stabilization projects railway bedding and many other applications 2 This test method determines the specific gravity of coarse aggregates that have been soaked for a period of 15 hours (Figure 1) There are four determinations that may be made from this procedure They are as
specific gravity (Gsb) of fine aggregates the Thermolyne SSDetect and InstroTek Corelok Each proposed method was evaluated against the standard method described in AASHTO T-84 The evaluation was based on a round robin study with twelve labs and six materials four crushed fine and two uncrushed (natural) fine aggregate sources
