Importance of unit weight of aggregate or more known as bulk density of aggregate is as described below. 1. Concrete Mix Design. In early ages, the bulk density of aggregates was used to determine the proportion of concrete mix in the concrete mix design. Higher bulk density results in a lower void ratio.

Crushed Gravel #2: Approx 1½ ″ to 3″ Wide. Crushed rocks in grade no. 2 usually range from 1½ inches to 3 inches in diameter, so, depending on your supplier, may contain larger gravel stones that, like #1, are not easy to work with and will need to be moved as individual pieces. Uses of gravel #2 include the following:

Key Features: If the volume is unit then, Bulk Density= Mass. Unit in kg/m 3 or lb/ft 3. In this definition, the volume contains both the aggregates and the voids between aggregates particles. The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m3 (75-110 lb/ft3) .

Stone, crushed weighs 1.602 gram per cubic centimeter or 1 602 kilogram per cubic meter, i.e. density of stone, crushed is equal to 1 602 kg/m³.In Imperial or US customary measurement system, the density is equal to 100.0096 pound per cubic foot [lb/ft³], or 0.92601 ounce per cubic inch [oz/inch³] .; Bookmarks: [ weight to volume | volume to …

The procedure provided in this article is based on the specification of ASTM standard ( ASTM C 29/C29M-17a). […]

fill materials materials the particles cannot move past each other to achieve density. Too much moisture leaves water-filled voids and subsequently weakens the load-bearing ability. The highest density for most soils is at a certain water content for a given compaction effort. The drier the soil, the more resistant it is to compaction. In a
