Original Abstract

This paper presents the results of research focused on the application of nanoparticles to cement composites. The effect of the addition of carbon nanotubes (CNT) on the mechanical properties of cement composites has been verified. Five recipes were tested to compare the effectiveness of CNT, one of which served as a reference, and the remaining contained different amounts of CNT (0.001 %, 0.005 %, 0.01 %, and 0.05 % by weight of cement). The compression strength and flexural strength of cementitious composites were monitored. The best results in the determination of the compressive strength were achieved at a rate of 0.01 % CNT for the amount of cement. For flexural strength determination, the best results were achieved with 0.01 % and 0.05 % dose of CNT. The optimal dosing of TNM7 multilayer CNT based on the executed formulations ranged from 0.01 % to 0.05 % by weight of the cement. The CNT dose in order of centesimal per cent of the weight of the cement had a significant effect on the flexural strength (after 28 days an increase of approximately 19 %), as well as on compressive strength, where the compressive strength showed an increase of about 9 % after 28 days.
