Using of Ultrasonic Pulse Method for Prediction of Strength of Blended Cements

One of the ways how to rationalize the experimental work is to put to use the non-destructive testing methods. In case of the strength testing of the various age cement specimens the usage of the ultrasonic pulse method appears to lead to decrease the necessary amount of tested samples. Application of this method requires fixed initial conditions like constant proportion of components, identical testing samples and constant sample’s condition during the testing. The methodology of testing and also the calibration correlations for the compressive strength or tensile bending strength and propagation velocity of ultrasonic pulses, are mentioned in this paper.
