Summary:The paper presents a standard vibrating table for fresh concrete testing adopted for determination of maximum dry density (ρ ) of sand. Vibration is an efficient method for coarse soil compaction therefore vibrating tables are useful for ρ determination. Acceleration that the soil is subject to is one of the basic parameters of efficient compaction. A vibrating table with inertial excitation was supplemented by a frequency converter and subjected to dynamic tests. The results of measurements of dynamic parameters are included. The paper presents problems connected with this method and describes the relationship between efficiency of compaction and accelerations which the soil is subjected to.
