This study presents an experimental research conducted to inspect the impact of partial substitution through the usage of nano silica (NS) and metakaolin (MK) on cement mortars (CMs). Besides to, the effect of the additive usage such as polypropylene (PP) on the dynamic and physicomechanical properties of CMs as single and combined effect. CM was formed through the usage of different substitution ratios of nano silica varying from 2 to 6% and metakaolin varying from 10 to 30 wt %, by cement weight, where the considered content for PP fiber was at 0.2%. Scanning electron microscopy (SEM), ultrasonic pulse velocity (UPV), flexural strength, and Compressive strength analysis are demonstrated in this paper. Results illustrated that, physicomechanical and dynamic properties of CMs positively enhanced as a result of using a mixture of PP, nano silica, and metakaolin. The CMs that included 0.2% PP, 4% NS, and 20% MK, showed the highest impact on physicomechanical properties compared to other mortar specimens.
