Abstract: Concrete setting and hardening process are the most critical phases during construction work, influencing to properties of concrete structure, so the application of efficiency non-destructive test methods for early age concrete properties determination is crucial. Penetrometer, pull out and Vicat needle methods are standardised methods for young concrete characterisation. Paper shows that ultrasound methods have potential to be used for these purposes. Measurements of longitudinal compressive wave velocity through concrete and mortar during hardening process are performed. For mixtures preparation different additives were used. Obtained results indicate possibility for hardening process monitoring and time of cementitous materials setting determination.
