Analysis of the Mechanical Performance of High-Strength Nano-Modified Cement Mortars for Overlays

This article provides the results of the analysis of the mechanical performance of high-strength nano-modified cement mortars for overlays. In order to find the optimal addition amount of those nanoparticles for which an improvement in the mechanical performance of high-strength nano-modified cement mortars for overlays in floors will be noticeable in terms of their mechanical, functional, and adhesive properties, the mechanical performance ratio (MPR) was used. Mechanical performance analyzes were carried out for the six most common variants of overlays. It has been shown that from the point of view of the mechanical performance of the high-strength overlay, it is optimal to use the addition of SiO2 nanospheres in the amount of 0.5% and TiO2 tetragonal crystalline nanoparticles in the amount of 1% of the cement mass.
