Influence of Silica Nanoparticles on Mechanical Properties of HPC

Abstract:

Nanotechnology proved to be a useful tool that can significantly improve the mechanical properties of ultra-high performance concrete. This paper presents the results of a long-term research which is focused on the influence of SiO₂ nanoparticles on the mechanical properties of high performance concrete. Three types of HPC specimens with a weight content of 0%, 1% and respectively 3% silica nanoparticle were prepared for flexural and compressive tests. SEM analysis was done in order to understand the effect of silica nanoparticle dispersion inside the cement matrix. The aim of this paper was to investigate the nanoparticles dispersion and how it affects concrete’s mechanical properties.
