Abstract The invention relates to a method and an arrangement for measuring the properties, particularly the degree of compaction of a stiff compactable mass, such as fresh concrete to be cast and similar soil mass. In order to make the control of compaction more effec- tive, gaseous pressure fluid is blown through the mass during the compaction of the mass, simultaneously ob- serving increase in the pressure of the gaseous press- ure fluid in the surface portions of the mass due to increasing flow resistance. The pressure fluid is blown through an opening formed in a wall adjoining the mass to be compacted and by means of a source of pressure fluid connected to the opening. Changes in the flow resistance are measured by means of a measur- ing device.
