  • Density of Aggregate Bulk and Relative Density Civil

    The relative density (specific gravity) of an aggregate is the ratio of its mass to the mass of an equal volume of water. Relative Density = Mass of the Aggregate / Mass of equal volume of water. Key Features: Most aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m 3 (150-181 lb/ft 3).

  • What Is The Unit Weight Of Crushed Stone

    voids, settlement and weight of crushed stone by ira 0. BAKER, PROFESSOR OF CIVIL ENGINEERING INTRODUCTION Crushed stone has become an important material of construc-tion in modern engineering work. The chief causes for this are the great increase in the use of plain and reinforced concrete, and the increased activity in macadam road construction.

  • Density of 3" crushed rock Earthwork/grading engineering

    Jul 01, 2008· Bear in mind coarser soils have a lower void ratio than finer soils. So, just because you can see the voids of a large aggregate material, does not mean the void ratio is greater than a fine grained soil. Given a void ratio of 0.3 and a specific gravity of 2.7, the dry density would be: GammaD=0.7*62.4*2.7=118 pcf
