The evaluation of stone quality by means of non-destructive tests is of vital importance,
especially when rock is used as a building material. Usually, however, only vp (P-wave …

There is a growing interest at an international level in non-destructive testing of cement
based materials, such as: impact-echo, pulse-echo, ultrasonic pulse velocity, wave …

The effect of the Interfacial Transition Zone (ITZ) on ultrasonic wave attenuation and velocity
in concrete is investigated in this study. These two parameters are often used to characterize …

The cold sintering process (CSP) densifies ceramics below 300° C by utilizing a transient
phase and applied pressure. Although CSP has been employed for densifying a variety of …
