RE: crushed stone voids. SirAl (Geotechnical) 7 Jul 03 23:19. It depends upon the specific gravity of the stone as well as the gradation. I use a dry rodded unit weight of 1630 kg/m3 and a specific gravity of 2.68 for the gravels in my location. That would equate to a void ratio of about 0.62 ignoring the pores on the face of the aggregate ...

crushed stone of all sizes has a 38 to 40% void space, allow-ing for substantial subsurface water storage. • it must be crushed stone, not rounded river gravel. Rounded river gravel will tend to rotate under pressure, causing the surface structure to deform. The angular sides of the crushed stone will form an interlocking matrix, keeping the ...

Crushed stone: If you hear the generic "crushed stone" term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.

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. The advances made …

For instance, if you needed 100 cubic feet of mortar (as measured from dry sand), then depending on the pore and void space in the sand your finished mortar could be as little as 83 cubic feet. If you (inadvisably) used crushed rock instead of a sand, it could produce as little as 75 cubic feet of mortar…and be structurally suspect.

With a more properly graded 3/4" washed stone (such as a good filter stone ranging between the 3/8" and 1" diameter), you will have a loose drop of more like 75%, but you will also actually be able to get closer to without talking about your subgrade. If the subgrade is sandy, it will not invade such a well graded gravel as much.
