اقرأ أكثرThe bulk density of fine aggregates is typically between 1300-1700 kg/m3 (80-100 lb/ft3). However, it may vary depending on the specific properties of the aggregates such as moisture content, compaction, and grading. In general, denser aggregates have a higher bulk density, while lighter aggregates have a lower bulk density.

اقرأ أكثرDensity is also called as unit weight of substance. It is represented by symbol called row ( p). Density represents the degree of compactness of material. If the material is of more density, it is more compacted material. Density is defined as the ratio of mass to volume. p = m/v Units = kg/m 3 or lb/ft 3 Conversion: 1 kg/m 3 = 0.624 lb/ft 3.
اقرأ أكثرThe bulk density of cement can vary depending on factors such as the type of cement, the particle size distribution, and the degree of compaction. In general, the bulk density of cement ranges from 1000 to 1300 kg/m³ (62.4 to 81.1 lb/ft³), with an average value of around 1200 kg/m³ (74.9 lb/ft³).
