It is because the process of excavation breaks up the compacted material. The excavated volume includes empty spaces and so it larger.
The volume of 1 m^3 of compacted sand remains 1 m^3. Compacted sand retains its volume despite its density or state of compression.
A bulking factor in excavation refers to the increase in volume of excavated material compared to its original in-situ volume due to the disturbance and loosening of soil or rock during the excavation process. When materials are excavated, they typically expand because air fills the spaces between particles, resulting in a larger volume. This factor is crucial for construction and engineering projects as it helps estimate the amount of material that will need to be managed, transported, or disposed of. The bulking factor varies depending on the type of soil or rock and the method of excavation used.

I don't know, you tell me...
Bulking of soils refers to an increase in the volume of soil when it is excavated or disturbed. This increase in volume is mainly due to the void spaces in the soil structure getting filled with air when it is excavated, causing the soil to expand. Bulking can affect construction projects as it can lead to inaccurate volume estimates and compaction issues.
Density can be thought of as how compacted something is. Density is calculated by mass divided by volume.
The volume of loose soil required to produce 1 cubic meter of compacted soil depends on the compaction ratio, which varies based on soil type and moisture content. Generally, loose soil can occupy about 1.2 to 1.5 times the volume of compacted soil. Therefore, for 1 cubic meter of compacted soil, you might need approximately 1.2 to 1.5 cubic meters of loose soil. This means that the exact volume can vary, so it's essential to consider the specific characteristics of the soil being used.
of Compress, Pressed together; compacted; reduced in volume by pressure., Flattened lengthwise.
dry , wet that's all sometimes still can be the answer
Not necessarily. Density is determined by the mass of an object compared to its volume. Heavier objects may have a higher density if they are more compacted, but lighter objects can also have a high density if they are very compacted or have a smaller volume.
In construction, bulking refers to the increase in the volume of materials, particularly soil or aggregates, when they are disturbed or excavated. This phenomenon occurs due to the loosening of particles, which creates air pockets and increases the overall volume compared to its compacted state. Understanding bulking is essential for accurate calculations of material quantities and for effective project planning and execution. Proper accounting for bulking ensures that sufficient materials are procured and that projects remain within budget and schedule.
really.. the answer is that the volume also gets larger
