If this 10 bank cubic yard or 13 loose cubic yards is compacted its volume may be reduced to 08 com pacted cubic yard and the weight is still lb Instead of dividing by 1 Swell to determine bank volume the loose volume can be multiplied by the load factor If the percent of material swell is To assess the degree of compaction it is important to use the dry unit weight γdry because we are interested in the weight of solid soil particles in a given volume not the amount of solid air and water in a given volume which is the bulk unit weight

Bulk density WikipediaRoadway Fill Volume Calculator
The bulk density of soil depends greatly on the mineral make up of soil and the degree of compactionThe density of quartz is around 265 g/cm³ but the dry bulk density of a mineral soil is normally about half that density between 10 and 16 g/cm³ Soils high in organics and some friable clay may have a bulk density well below 1 g/cm³Calculate US or SI units of volume tonnage and price of roadway fill such as clay gravel sand or other roadway construction materials Allows common road materials or custom entry so you can enter your own material density Gravel dry loose Gravel natural with sand Gravel dry 1/4 to 2 inch

Gravel loose dry density in 285 units of density measurementSoil Moisture Content Dry Density Relationship
Gravel loose dry weighs gram per cubic centimeter or 1 522 kilogram per cubic meter ie density of gravel loose dry is equal to 1 522 kg/m³ In Imperial or US customary measurement system the density is equal to pound per cubic foot lb/ft³ or ounce per cubic inch oz/inch³ Compaction Curve Compaction curve is plotted by taking moisture content on x axis and dry density on y axis Required amount of soil is collected from the field and compaction test performed in the laboratory The results obtained are used to draw the compaction curve as a result the amount of compaction required will be known

Powder Density Tapped Density / Powder Bulk DensityWhat is the difference between bulk density tapped
The bulk density the tapped or tap density and the Hausner ratio measurement is very popular for powder characterization because of both the simplicity and the rapidity of the measurement Moreover the density and the ability of a powder to increase its density are important parameters for storage transportation caking etcThe bulk density of a powder is the ratio of the mass of an untapped powder sample and its volume including the contribution of the inter particulate void volume Hence the bulk density depends
