When sediment particles press together.
Compaction is a process of expulsion of air.Ex: Expulsion of the entrapped air from concrete.
In the lithification process, compaction is followed by cementation. It is the hardening and welding of clastic sediments by the precipitation of mineral matter.
The process is called compaction and that is when the mineral grains are pressed together but have pore spaces in between and hot fluids can pass through. Cementation is when they are fully glued on and there aren't any pore spaces.

The process is called lithification, which involves the compaction and cementation of sediment to form sedimentary rock.
The process you are referring to is called compaction. Compaction occurs when the weight of overlying sediments forces out water and air, reducing the volume of the sediment and causing grains to come closer together.
Diagenesis is the process that involves burial compaction and cementation of sediment.
