The present work proposes to use ultrasounds as a non-destructive method of control applied to cement mortars whose composition is quantified and defined by weight, as a preliminary tool of investigation used to minimize the manifold factors (curing conditions, composition, age, [etc].) affecting the search for the strength/velocity relationship in the definition of possible curves of reference for the characterization of mortars in types and classes of the main products of the cement industry. The formulation of the above mentioned criterion, used to seek a relationship between the two magnitudes of velocity and resistance, extended to the non-destructive control on a meaningful number of samples consisting of prismatic samples of cement mortar manufactured with different types of binder, prepared for the scopes of Service for the Control of Cements’ Quality of ICITE, becomes functional if curves of correlation of type R = KVare assumed and made explicit on every representative specimen of each of the different examined cement mortar types. According to this assumption, the interpolation of the laboratory data, ordered with the same cumulative frequency, on each specimen representing the individual type of cement mortar has allowed to establish the appropriate “K” and “” parameters of the investigated curves of correlation, expressing the relationship between the velocity of propagation and the compressive strengh of the most meaningful compositions (M1 with different type of cement) of cement mortars.
