Void Ratio Of Crushed Gravel

Void Ratio Of Crushed Gravel

Void Ratio for Common Gravel amp Sand Sciencing. Gravel Gravel typically has a void ratio about 0.4, regardless of whether it is well or poorly graded, although the void ratio can be affected by the presence of impurities, such as clay or silt. Gravel with clay has a void ratio of about 0.25, while gravel with silt can have a void

Soil Voids Soil voids are that portion of a soil volume not occupied by solids. In a natural state, the voids may be filled by liquid, gas, or both. Gas in the voids is usually air. In soil engineering, air in voids is treated as being weightless. Liquid in the voids is usually water, which is considered incompressible. Origin

Art 31 Voids In Sand

256. Conditions Affecting Voids. The voids present in a given mass of sand will depend upon the shape of the grains, the degree of uniformity in size of grains, the amount of moisture present, and the amount of compacting to which the mass has been subjected. If all of the grains in a given mass of sand are of uniform size, the percentage of voids will be independent of what that size may be.

The volume of the water used to fill the pail was 78.54 X 5.75, or 451.6 cubic inches. This is 41 per cent of the volume of the stone, and is in this case the percentage of voids. The accuracy of the above computation depends largely on the accuracy of the measurement of the mean inside diameter of the pail.
