Abstract
The paper presents the preliminary results in terms of strength and dynamic elastic properties obtained on mortar prisms. The bending tensile and the compressive strength of regular and carbon nano-tubes (CNT) mortar were determined by means of standardized tests at the age of 28 days. Prior to assessing the strength value, non-destructive testing was used to determine the dynamic elastic characteristics, namely dynamic longitudinal modulus of elasticity and material damping ratio. The use of CNT in the mortar mix led to a reduction in the self-weight. However, the surfactant used to ensure the uniform dispersion of CNTs had a detrimental influence on the mechanical properties of mortar.
