English abstract
In the article is given estimation of the application of an ultrasound for determining the strength of gypsumfree portland cement. Are analyzed the factors, which have influence on the results of measurements and condition, under which are conducted the measurements. The authors furthermore developed test procedure. The results of tests made it possible to develop calibration dependences for determining the compressive strength on the basis of the speed of ultrasound. Calibration dependences for determining the bending-tensile strength on the basis of the speed of ultrasound, it was not possible to determine since strengths in the age 7 - 28 days reach maximum, and then they are lowered.
