The present work proposes the use of the ultrasounds, which method of control not destructive applied on mortars of cement [ponderalmente] quantifies and defines in their composition, like preliminary tool of investigation for minimize the manifold factors (conditions of maturation, composition, age, [etc].) that they influence the research of the bond strength/ velocity in the definition of possible curves of reference for the characterization of the mortars in types and classes of the principal products of the industry of the cement. The formulation of the standard above indicated, for the research of a relationship between the two greatness velocity and resistance, wide to the control not destructive I on a meaningful number of samples constituted from prismatic samples of mortar of cement manufactured with different type of [legante], predisposed for the finalities from the Service Control Quality Cements of the Icite, it becomes functional if they are taken on and they are explicit curves of correlation of the R type= KVa on every representative specimen of each of the different types of mortar of examined cement. With this hypothesis, the [interpolazione] of the data of laboratory, ordered with same cumulative frequency, on each representative specimen the single type of mortar of cement has allowed to establish the appropriate K parameters and to of the curved wanted of correlation, expression of the bond between the velocity of propagation and thecompressive strengh for most meaningful compositions (M1 with different type of cement) of mortars of cement.
