Natural sand is collected from river Basin and manufactured sand (m sand) is made crushing of stones in Crusher mill. Locally available river sand have density 1710 kg/m3 is used and specific gravity is 2.65 and finance of modulus of river sand is 5.24. ... Relative density = Mass of the aggregate / Mass with an equal volume of water.

relative density for crusher sand - piotrbarc.pl. relative density for crusher sand Dec 01 2015 Relative Density or Density Index Test of Sand Purpose This lab is performed to determine the relative density of cohesionless freedraining soils using a vibrating table The relative density of a soil is the ratio expressed as a percentage of the difference between the maximum index void ...

Essential Points. Most of the aggregates possess a relative density within 2.4 – 2.9 with a similar particle density about 2400-2900 Kg/m 3 (150-181 lb/ft 3).; Hereabouts, for coarse aggregates, the standard test process has been described in ASTM C 127(AASHTO), and for fine aggregates, the standard test practice has been described in ASTM C 128 (AASHTO).

Relationship among relative density, SPT N value, and internal friction angle of cohesionless soils (after Meyerhof, 1956). state of packing relative ...

Relative Density of Aggregate [1] The relative density (specific gravity) of an aggregate is the ratio of its mass to bulk density of crusher sand and aggregate,Distinction is made between the density of aggregate particles and the bulk density of aggregates as …

The Density of Sand utility returns sand density based on sand conditions (wet/dry in bulk / packaged).. The density of the sand is affected if the sand is compacted (bulged) or loose and if it is wet or dry.When packed, the grains of sand are forced to form a narrower formation, and more matter is in the volume.. Natural sand i.e. locally available River sand having a bulk density of 1.71 kg ...

the ASTM Method D 2049 (Relative Density), the Washington Spring-Loaded Vibratory Compactor Method, the Marshall Hammer Test, and the Gyratory Compactor Procedure. The aggregates tested were a granite-gneiss, a crushed gravel, a dolomitic limestone, and a basalt. A prototype field compaction 'testing program was conducted using the same

Density limits as a function of grain shape for laboratory fractions with C u ¼ 1 .4 (Youd, 1973) 197 ... sand when relative density is 70%. Conversely, a blow count of 20 indicated a spread in relative densities from 66 to 86%. More recently, Liu and Lehane ...

Relative density of soil formula. Where, e max = maximum void ratio. e min = minimum void ratio. e = soil at some void ratio. When soil is very loose, e= e max and D=0. When soil is very dense, e= e min and D=. If we plot graph of e max /e min against D=0 and D=1, a curve is obtained as:

Relative density is an arbitrary character of sandy deposit. In real sense, relative density expresses the ratio of actual decrease in volume of voids in a sandy soil to the maximum possible decrease in the volume of voids i.e how far the sand under investigation can be capable to the further densification beyond its natural state.

From the compaction curve it can be seen that sand attained a maximum dry density of 1.82 g/ccat optimum moisture content of 6%.Comparing the above characteristics of crusher dust with sand, crusher dust attained higher densities with wide variation of moisture contentsby maintaining well graded conditions with C u as 23>6and Cc as 2.78>1.

Using relative density as an indicator of sand condition, geotechnical engineers have performed many research studies of sand behavior by placing sands at differing relative densities. By measuring the in-place density of alluvium and determining its relative density, a judgment can
