Sažetak
Calcium aluminate cement (CAC) mortar was investigated by nondestructive ultrasonic measurement in the through-transmission mode and compressive strength measurements. The detected profile of ultrasonic signal was fitted as a sum of two functions of the following form: U(t)= A sin(ω t+φ ) exp(-(t-tc)2/w2). From the fitted ultrasonic wave signal one obtains wave packets group velocity, angular frequency and envelope amplitude. The product of those parameters is proportional to the stress induced in the cement material and it was found experimentally to be proportional to the compressive strength of the material.
