What happens to soil volume when it is compressed?

When soil is compressed, the volume is reduced due to the rearrangement of soil particles and the expulsion of air or water from the pore spaces. When external pressure is applied to the soil, the particles come closer together, leading to a decrease in the overall volume of the soil mass. This behavior is typical for granular soils and clayey soils, where the structure can change significantly under compressive forces. In contrast, if volume were to increase, it would imply that the soil is somehow expanding, which is contrary to the behavior observed during compression. A constant volume would suggest that compression is having no effect on the soil structure, which is not accurate either. Furthermore, fluctuations in volume would indicate a varying response to pressure, which is not representative of the consistent outcome seen in soil compression. Thus, reducing the volume is a fundamental characteristic of soil behavior under compression.
