Szukana fraza: [Abstract = "The first method is based on the measurement of the velocities of the surface ultrasonic waves and the second by tearing tests using a specific dynamometer. The determination of the adhesion strength concerned two different supports \(concrete beam and masonry block\) coated with two types of mortar \(a prepared cement mortar and a ready\-to\-use mortar\) with two different thicknesses for each mortar \(1 and 2 cm, respectively\). The results of the two methods are then correlated for an estimation of the adhesion of the mortars."]
