ABSTRACT
The study focused on comparing mortars made with Hs and Type N cement. The main objective was to investigate the effects of adding nano-iron in different percentages (0.25%, 0.50%, 0.75%, and 1.00%) to replace part of the cement. Mechanical tests were carried out, including simple compression, indirect traction, and impermeability tests, following the procedures stipulated by the relevant ASTM and NTE regulations. Additionally, detailed microstructural analyses were conducted using advanced techniques such as X-ray diffraction and scanning electron microscopy, allowing for a more precise characterization of the morphology and distribution of iron nanoparticles in the mortar. The results show that the addition of nano-iron significantly increases the mechanical properties in the hardened state of the mortar. Nano-iron improved mortars’ strength, reduced porosity, and enhanced uniformity. However, a decrease in plastic state properties was detected, especially in the workability of the mixture, attributed to the agglomeration of the nanoparticles.
