The creep of cement paste is one of basic material properties which is important for design of concrete structures. In the paper are described experimental results of measuring of the cement pastes creep. For measuring was selected cement CEM II and prepared pastes wit water cement ratio from 0.3 to 0.5. Creep of pastes was measured on water saturated, water dried specimens. Shrinkage of different cement pastes was measured too. Finally, mechanical properties of material were measured. Measurement of specimens for testing was for cylindrical specimens with diameter 10mm and length 70 mm. Small specimens were tested in the special creep test equipment and in the electromechanical testing equipment for the uniaxial compression tests. History of creep, material properties, history of specimens are used like an inputs for simulation by finite element method.
