The reduction of voids in soil material results in which of the following changes?

The reduction of voids in soil material leads to an increase in unit weight. Void spaces within soil consist of air and water, which occupy part of the total volume. When the voids decrease, more of the volume is occupied by the solid particles of soil, ultimately increasing the overall density of the material. This increase in density directly translates to an increase in unit weight, as unit weight is defined as the weight of the soil per unit volume.

Higher unit weight has significant implications in various civil engineering and geotechnical applications, as it affects the soil’s load-bearing capacity and stability. These principles are essential to understanding soil behavior under different conditions, particularly in construction and earthwork projects.
